Martinez is doing great. But he is not perfect. He has a few times during the game reverted to old habits. A few times his form wasn't correct, still shot-putting the ball. A few times he stared down receivers. So Martinez is doing a good job out there and has the stats to prove it, but he still reverts to old habits that sometimes get him in trouble.
What? Really, what more do you want from the kid? Nobody is going to be perfect. Drew Brees is arguably one of the top 2 quarterbacks in the NFL and I believe he has thrown a pick in every game this season. Martinez is getting the job done, and aside from the OSU game it's been pretty efficient and pretty dang good.
