Jonathan Chait wrote a column for The Wolverine. He explains why he doesn't think Ezeh is cut out for linebacker and then suggests that he should move to DE or Quick. FWIW, he also mentions that this probably won't happen.
It's too late for Ezeh to move. He's too small for DE and he would be overwhelmed by offensive linemen. And we already have a good player at Quick in Craig Roh. On top of that, removing him from the middle linebacker competition would leave us with Fitzgerald, Demens, Bell, and Leach to cover those two positions. In other words, one decent player, a former walk-on, a converted safety, and Demens, who's been unable to earn playing time the past couple years, despite the poor ILB play.
This would weaken us at one position (MLB) and wouldn't help at any other position because he'd be a second-stringer at best. It's a lose-lose situation. Just keep him at MLB and hope everything clicks.
