I agree with
@Rdforty2
I could see them trading away Mason now. There is no reason for Wynn to sit. If the plan is for Brown/Cannon to be the starting tackles (maybe Garcia) then you have Thuney/Mason/Andrews/Wynn on the interior. 4 legit starters.
If you move Mason now you can get a high 3rd for him I think. If they keep him this year and let him walk maybe they get a comp 4th but more likely a comp 5th.
Now if Wynn is your long term solution at LT and Brown was just to have a quality back up it makes all the sense in the world to keep Mason this year. Bottom line is if for any reason Wynn isn't on the field this year then someone screwed up. You don't sit the 23rd overall pick unless it is a QB.
