Freshmen QBs as well as Freshman and Sophs scattered throughout the team that play significant minutes are going to make plenty of mistakes mixed in with those 'special' ones. There are going to be more than enough of those learning situations and teachable moments. Frost's offense from what I gather from watching a few games and listening to his comments as well as many comments on this board requires, above all else, a QB to make QUICK, CORRECT decisions both before and after the snap. QBs who throw to the wrong place or player after misreading the defense or when his receiver runs the route wrong, or bobbles the snaps or messes up the timing on a simple handoff, cause bad plays including turnovers. Those, as we saw last year (Tanner Lee's pick six routine), are game losers. The defense will need to rise up to get some keys stops and hold opponents to field goals.
It may be that Frost will need several QBs to come into the early season games depending on conditions and confidence, etc. This won't be an easy decision to start a true, raw freshman or redshirt frosh, each with only 8 months to learn what appears to be a very complex position. I think Martinez and Gebbia are confident in themselves but when the errors happen, it will be key for the individuals, the team and coaches to keep encouraging and stay positive. They'll need to play without fear of making mistakes as Frost is stressing. Easier said than done for some guys. Character will be vital.
