Your thoughts on possible position switches in 2012

As we look ahead to the next season, who do you think is a candidate to switch positions? I know some people think Jake Ryan could move down to the defensive line (I'm not one of them), but who else do you think could end up moving around?

I'll throw one out there: Keith Heitzman to TE. With little depth at TE I could see this happening. He's currently listed as a DE, but he played TE in high school and is listed at 6'3", 251. We have a lot of depth at the DE positions, so it wouldn't hurt to move him.
