So much so that a fan who was wearing a polo shirt with the New York Giants logo asked for a photo with Darnold, who was selected with the third overall pick of the 2018 NFL Draft.
"We've got to get you a Jets polo," the 21-year-old Darnold said with a smile, per the New York Post. "That blue doesn't look good on you."
"We talk about it in the quarterback room all the time," Darnold said, per the newspaper. "Whenever we get a chance to watch greatness, whatever it is, you learn from it -- even last weekend with Justify winning the Triple Crown. You appreciate that.
"As a quarterback and someone who's striving to be great, it's crazy to see guys like Dustin Johnson able to do what he does. It's just so cool to watch greatness in action."
Darnold hopes to be great with the Jets, who have limped to back-to-back 5-11 seasons and haven't made the playoffs since consecutive trips to the AFC Championship Game following the 2009 and 2010 campaigns.
New York's desire for a top-tier quarterback was on display after the team made a blockbuster pre-draft trade with the Indianapolis Colts to move up three slots to No. 3. It was a hefty price to pay as the Jets sent the No. 6 pick and a pair of second-round selections (No's. 37 and 49) this year along with a second-round pick in the 2019 draft to the Colts.
From the team's perspective, the gamble paid off when Darnold, considered the top quarterback in the draft by NFLDraftScout.com senior analyst Rob Rang, fell to them at the third spot.
Darnold completed 303 of 480 passes for 4,143 yards, with 26 touchdowns and 13 interceptions with the Trojans last season.
Allen, who is listed at 6-foot-5, 237 pounds, threw for 1,966 yards with 19 touchdowns last season at Wyoming.
