It's even more rare to see the coach in such an expressive state in the middle of the regular season.
But Belichick was almost smitten with the work his team put forth over the last week-plus with a 41-16 win in Denver followed up by Sunday afternoon's 33-8 blowout of the Raiders in Mexico City.
In between, there was a week of practice at the United States Air Force Academy in Colorado Springs on a rare, true NFL road trip.
"I'll always be a Navy man, but just wanted to give a shout out and a big thanks to (Lt.) General (Jay) Silveria and his great staff at the United States Air Force Academy for the hospitality and the week we had there," Belichick said, wearing an Air Force hoodie at his postgame press conference after dominating Oakland.
"This has been a three-leg trip for us and we asked a lot of players, asked a lot of our organization and they all delivered. We had a great nine days. We really got better as a football team. We met all the challenges we needed to meet head on.
"Our players gave a great effort tonight. They came out and performed well early and throughout the game and played great situational football. Credit to the team and the entire organization, all the people planning this trip. It's good to be going home with two wins on this trip."
Now tied with the Steelers for the best record in the AFC at 8-2 thanks to a six-game winning streak, New England is clearly playing its best football of the season.
After a month with a lull in scoring, Tom Brady and Co. were back in the 30-plus-point mode the last couple weeks, when the quarterback completed six touchdown passes with no interceptions. Defensively, the Patriots have held opponents to 17 points or less in six straight games after allowing 33 or more in three of the first four games of the year.
To a man, players and coaches alike believe that hard work has paid off and led to game-day performances.
"It was a fiesta all over the field," tight end Rob Gronkowski said, getting into the spirit of the big win at Estadio Azteca with a nod to both the support New England got from fans as well as the performance of the team itself.
"These trips all come down to whether you win or lose," Brady said. "You remember when you win. If you lose you want to forget as fast as you can."
As happy as Belichick and his players were with the latest win and winning streak, the coach reined in the positivity after reviewing the film and preparing to turn the page to Sunday's post-Thanksgiving game against the Dolphins at Gillette Stadium.
"I think the players have worked extremely hard. We've had our moments," Belichick said of the mid-season improvements and winning streak. "There's still a lot of things that we need to work on and need to improve in.
"Each game gets a little more demanding because your opponent has had another week of things that you know they've shown and you have to work on, and so the volume builds up. Of course, our volume has built up over the last 10 weeks, too. We just have to keep grinding away week by week, and that's what we'll try to do."
Kicker Stephen Gostkowski nailed a 62-yard field goal as time expired in the first half in Mexico City, taking advantage of the thin air at 7,200 feet to best his own 58-yard Patriots franchise record that he set earlier this season. It was a kick, one of four field goals on the day, which probably would have been good from another 10 yards or so.
"It was cool," Gostkowski said afterward. "With kicking, you can wait your whole career and never get a shot like that. You have to be very patient. It's a very opportunistic job, and you're only as good as the opportunities you get. I got a good opportunity, and I'm glad I took advantage of it.
"It was just a fun experience to have a hand in the win. To see the excitement in all the guys after making that kick was pretty cool."
This opportunity came to impressive situational football by quarterback Tom Brady and the offense. Taking over at their own 7 with 33 seconds to play in the second quarter, Dion Lewis burst for a 20-yard gain, wide receiver Danny Amendola had an 18-yard catch and tight end Rob Gronkowski had a 10-yard reception to the Oakland 45.
"I think every time I've kicked a long kick, Gronk made the catch right beforehand, so it's a nice little Polish connection," Gostkowski joked.
Head coach Bill Belichick notched his 271st career win with the 33-8 blowout of the Raiders in Mexico City, moving past Cowboys legend Tom Landry into third place in NFL history for all-time wins behind Don Shula (347) and George Halas (324).
Patriots owner Robert Kraft presented his coach with a game ball after the historic win, though Belichick deflected the attention afterward.
"Really, that's a credit to our players; players win games," Belichick said. "They're the ones who go out there and make the blocks, the tackles, the runs, the throws, the kicks. I think what it means is, No. 1, I've been doing this for a long time, and No. 2, I've coached a lot of great players. I've been very fortunate to have a great coaching staff, great assistant coaches and great players. I've had a great opportunity to direct those people and, really, the credit goes to the players.
"They won the game tonight and they deserved to win because they played better. That's the way it's been on those 270 games or whatever it is. I've been fortunate to have a lot of great players."
Former Patriots first-round pick and Pro-Bowl wide receiver Terry Glenn died in a car accident in Texas in the early-morning hours Nov. 20. Glenn was drafted with the No. 7 overall pick out of Ohio State in 1996 and helped the Patriots to a Super Bowl that year with a then-NFL rookie record 90 receptions. His career in New England came to a tumultuous close in 2001 when he was suspended and dealt with hamstring injuries that limited him to just four games. He was traded to Green Bay that offseason and finished his career with the Cowboys.
Bill Belichick coached Glenn first as an assistant on Bill Parcells' Patriots staff in 1996 and then for two seasons as New England's head coach from 2000-01.
"I was pretty close with Terry," Belichick began. "His rookie season was my first year here in '96, so I had a lot of interaction with him and other people that were involved in his life and his upbringing separate from the Patriots. Terry was a very smart individual, had a lot of, obviously, a lot of physical skill and talent, could do a lot of things on the football field very naturally. I think he was deep down inside a good person with good intentions and a good heart. Obviously, it's a very unfortunate passing. I mean, it's just sad. It's a sad day. It's sad news."
"We were shocked and deeply saddened by today's news that Terry Glenn died in an auto accident," Patriots chairman and CEO Robert Kraft said in a statement. "Terry was one of the most gifted receivers we have ever had. For so many Patriots fans, his rookie season will be remembered as one of the most impactful in franchise history. After a disappointing 6-10 finish in 1995, we drafted Terry seventh overall, and in his first year, he helped propel the Patriots to an AFC Championship and Super Bowl appearance.
"One of my favorite memories came when we hosted the Pittsburgh Steelers in the divisional playoff game. It was my first home playoff game as an owner and just the second home playoff game in our history. It will always be remembered for the fog that filled Foxboro Stadium that day. Yet, on the first play from scrimmage, Drew Bledsoe threw a deep pass that disappeared in the fog and reappeared 53 yards downfield in Terry Glenn's hands. We scored on the next play and ended up winning 28-3.
"Our thoughts and prayers are with Terry's family, his former teammates and friends who mourn his loss."

REPORT CARD VS. RAIDERS
--PASSING OFFENSE: A - Tom Brady earned AFC Offensive Player of the Week honors for his work in Denver and was even better in Mexico City against the overmatched Raiders. Brady completed 30 of 37 throws, including his first 12 of the afternoon, for 339 yards with three touchdowns and no interceptions for a 131.9 rating, once again dominating a Jack Del Rio defense. Brandin Cooks led the receivers with six catches for 149 yards, including a 64-yard touchdown on the opening drive of the third quarter. New England's banged-up line was good once again, holding Oakland to just one sack.
--RUSHING OFFENSE: B - The ground game was a clear secondary focus against Oakland, but still productive to the tune of 20 attempts for 89 yards. Dion Lewis led the way once again with 10 carries for 60 yards, including a key 20-yard run very late in the second quarter that jump-started a drive to a long field goal as time expired in the half. New England was fortunate that Rex Burkhead's opening-drive fumble in the red zone was recovered by tight end Dwayne Allen.
--PASS DEFENSE: B - Despite once again failing to get much pressure on the passer, New England held Derek Carr to just 28 completions on 49 attempts for 237 yards with one touchdown and one interception. Carr had just 65 yards passing in the first half and was hindered by endless drops by his receivers all afternoon. An area of improvement, the Patriots allowed just two completions over 20 yards, while Duron Harmon hauled in a deflected interception.
--RUSH DEFENSE: C - Playing without defensive tackle Malcom Brown once again, New England's run defense was again shaky, especially before the score got out of hand. Oakland ran it 21 times for 109 yards (5.2 average) as a team. Marshawn Lynch led the way with 11 rushes for 67 yards, including a 25-yarder around right end, with nine of those rushes for 61 yards in the first half.
--SPECIAL TEAMS: A-minus - Stephen Gostkowski certainly enjoyed the thin air in Mexico City, nailing a 62-yard Patriots franchise-record field goal on the final play of the first half. He hit three other field goals (51, 40, 29) and six touchbacks on seven kickoffs. Ryan Allen punted just twice, both downed inside the 20 for a 47.5 net average. Neither team did much of anything in the return game.
--COACHING: B - Head coach Bill Belichick oversaw a two-week road trip in Denver and Mexico City that proved extremely productive. Offensively New England used a more down-the-field approach to the passing game after a few weeks of shorter passing action. Defensively, the unit continues to force/take advantage of turnovers while keeping opponents out of the end zone. Coordinators Josh McDaniels and Matt Patricia seem to be getting quite comfortable with their personnel and approaches on offense and defensive, respectively. That was certainly the case against Oakland.
