I'd be interested to know what Knowles/Poindexter think of Farooq and Walton. I think Walton has a lot of upside, just not sure how close he is to reaching it. Maybe they think they can get him there better/faster than the previous staff. Hell, maybe they think that about Beasley too. He looked awful last year to me, but we were told he was really good in fall camp. And he obviously hasn't been asked to leave.
Maybe this new defensive staff thinks 2 or 3 of those guys can be qualify pieces, so maybe they only want 1 starter from the portal (Lane) and another just for depth.
