Tanner Trosin has taken snaps in every game this year for Folsom High’s football team, usually when the game has already been won and starting quarterback Dano Graves has been taken out of the game. On Friday, however, Trosin might have a much larger role when Folsom meets Grant at 7:30 p.m. at Sacramento State for the Sac-Joaquin Section Division II championship. Graves injured his right knee in the win over Buhach Colony last week and Folsom coach Kris Richardson said Sunday it would be a game-time decision whether Graves plays or not, pending on the results of his MRI on Monday. If Trosin is called upon, one thing is for sure: he’s ready to do the job and his teammates and his coach believe in him. “I’m confident I can get the job done,” Trosin said. “I’ve got to be ready to go and I’ll make sure to do whatever it takes to be ready.” Trosin quarterbacked Folsom High’s freshman team two years ago and started four or five games for the junior varsity team last year. He’s played in every game this year, completing 13-of-18 passes for 256 yards and two touchdowns against two interceptions. He’s rushed the ball 41 times for 219 yards and three touchdowns and also caught nine passes for 69 yards and two scores. “I’ve gotten into games but haven’t really thrown the ball much because usually we’re just running the ball to run the clock out,” Trosin said. Trosin’s older brother, senior receiver and defensive back, Tyler, has faith in his brother. “I have a lot of confidence in Tanner to get the job done,” Tyler said. “We believe he’s the second-best quarterback in the section behind Dano. We’re really lucky to have him. We have trust and faith in him.” Senior running back and defensive back Jordan Richards agreed. “Tanner has showed us that he can play the position at a high level,” Richards said. “We’d love Dano to play and it would be unfortunate if he can’t, but Tanner will be ready.” Richardson also has faith in Trosin. “Tanner is no slouch; we believe he’s a star in waiting, one of the best quarterbacks around,” Richardson said. “The thing about him is that our game plan doesn’t change if he’s in there or if it’s Dano. I don’t know too many teams that can say that. Tanner has a great feel for the quarterback position and he can do the job.” Even Graves, who was battling Trosin for the starting position before last season began, believes in him. “If I can’t play, I have complete confidence in Tanner,” Graves said.
