For those of us who have been hoping for this day to come, rejoice because it is here. In a discussion with WDVE's Mike Prisuta, Colon confirmed that he will indeed move to left guard in order to make room for Mike Adams to start on the offensive line. ESPN speculates here that the new offensive line will look, from left to right like this:

Adams T

Colon G

Pouncey C

DeCastro G

Gilbert T

In my humble opinion, the guard position is the best fit for Colon and the team at this point, and significantly improves the OL, assuming Adams is ready to take over at

EDIT: Meant to mention this earlier. I don't think it's a coincidence that we're seeing Colon moving to LG with Adams at LT. I'm sure part of that is to help Adams adjust and for Colon to help teach him things as they go. Certainly should be a good way to go about it if you ask me. This seems like the best way to go on paper.
