The problem is, the guy who keeps making freshman mistakes is the same guy who is about to become Nebraska's all-time total offense leader, and QB of some of the most insane comebacks in Husker history. That doesn't exactly describe Grant and Lee.
Very true, but this also reminds me of Martinez in many ways. For all the incredible things he was able to do, and all the games he won/numbers he put up, he couldn't get out of his own way. Fumbles, interceptions, mistakes, you name it. TM did more good than bad, but he did a lot of bad.
TA reminds me a lot of TM in this regard. Overall, TA has done more good things than bad at Nebraska, but his lack of ball security and his inability to make substantial improvement makes him a detriment to the team, too. The fact that he'll likely become Nebraska's all-time total offense leader is in part due to skill, but also in part due to him having started an immense amount of games.
