GLENDALE, Ariz. -- Alabama running back Derrick Henry and Clemson quarterback Deshaun Watson took turns throwing haymakers in a riveting first half of the College Football Playoff Championship Game, and the teams were tied at 14 at the break.
The Heisman-winning Henry scored twice, including on a 50-yard run, and Watson fired two pretty touchdown passes to freshman receiver Hunter Renfrow.
Henry went over the 100-yard mark with 7:41 to go in the second quarter and rolled up 129 yards on 20 carries by halftime.
Watson, who was third in the Heisman balloting, kept Alabama off balance with his arm, his scrambles and a smattering of designed runs. He passed for 162 yards and ran nine times for 45 yards in the first half.
Each team missed 44-yard field goals, including Clemson in the final seconds of the half. Alabama defensive lineman D.J. Pettway got a hand on the attempt, causing it to fall short.
Alabama, which had allowed only 19 first-quarter points all season, gave up 14 to Clemson after the Tide took a 7-0 lead.
After the teams exchanged punts to open the game, Henry, on third-and-1 from midfield, took a handoff and made one cut to the right, where guard Alphonse Taylor and tackle Dominick Jackson opened a huge hole. With Clemson's defense pinching in, Henry got to top speed and ran past strong safety Jayron Kearse and into the end zone for a 7-0 lead with 7:55 to go in the first quarter.
Clemson immediately answered.
After the Tigers converted third-down plays on a pass-interference call and a Watson scramble, Watson lobbed a perfect 31-yard pass into the end zone for Renfrow, who slipped behind defensive back Minkah Fitzpatrick to tie the game.
That Clemson combination struck again on the final play of the first quarter, as Watson, on third-and-9 from the Alabama 11, fired to Renfrow on an in-route in the middle of the end zone. Once again, Renfrow beat Fitzpatrick on the play.
Alabama tied the game after safety Eddie Jackson's interception at the Clemson 42. Henry topped the drive by going airborne from the 1-yard line with 9:35 to go in the half.
In 16 BCS championship games and one previous CFP title game, there was only one halftime tie.
