It'll be an adjustment, like it is with any player. The good thing about a guy like Gathers, though, is the adjustments will be mostly mental. We should be able to use him in a very limited basis where we pretty much just take advantage of the physical mismatch he represents as we work him in.
Agree the Witten stuff is nonsense. He's at the end of his career, but he's playing pretty much just like he always has. People forget we relied on him fairly extensively earlier in the season. He's missed a few blocks, but again, our issues are not with the offense.
