Yes...And in my opinion they will be the starting guards next year. I am going to say that William Gass will take over at center and the tackles will be Chip Rhodes and Alec North.
On defense Clay Powers and Michael Sizemore will be the tackles, at the ends,,,,,not too sure.
I want to again say that this is only my OPINION based on what I have seen this season. As you know a lot of things can change from one year to the next.
