Harris started six games as a freshman after replacing starter Jeff Driskel midway through the season. A two-time state champion at Booker T. Washington High in Miami, Harris threw for 1,019 yards, nine touchdowns and four interceptions. He added 338 yards rushing and three touchdowns.
“Treon is going to start the football game and Will is going to play a lot, too,” McElwain said. “Both of them deserving of it. Both of them had a really good spring and fall. We’re excited about seeing those guys play.”
In his six games last season Harris completed 49.5 percent of his passes for 1,019 yards, nine touchdowns and four interceptions while rushing for 338 yards and three touchdowns.
Grier redshirted but was the Parade National Player of the Year in his senior year of high school and ranked as the No. 3 quarterback in the 2014 recruiting class.
