I commend Buchner for his tough, gritty performance against a depleted USC defense, and in all honesty he looked better than I expected with his long layoff.
But if we're honesty evaluating his performance there is a lot to be hopeful about BUT also a lot to be concerned about (and that's IF he stays healthy). But more to the point, there was nothing I saw in the Gator that made me think he has 'cemented himself' as the starter.
If we get Hartman, it should be an open competition between the two with best man wins. I (someone who has defended Buchner a lot) would be incredibly surprised if Buchner beat Hartman out in a legit QB1 competition.
