He looked ok at times and lost or overmatched a majority of the time. That could be from learning a new system on the fly, but he couldn't beat out anyone in Cleveland and its not like he was going against 1st rounders in training camp to lock down a spot.
Kromer cannot hurt, that is for sure, but Kromer is a coach, not a wizard. There is only so much he can do. My fear with Corbett is he had average at best play strength in college and it still seems to be his biggest issue. On top of that, he only played LT in college and maybe he just isn't an OG. It could really be that simple. Some guys transition, some don't. And when you lack power, it doesn't help.
