"That's partially because, if they can't hold JJ, then they can't defend him, unless they double him... "
Are you sure you want to make that claim about a guy who averages 3.2 receptions and 44 yards a game? I don't want to come off as mean, but it seems kind of silly to me along with the whole pass interference discussion. Both teams have great secondaries and both may grab a WR at the wrong time. That's just football. The calls should be too few and far between to be able to project in any reasonable way.
As for covering Jones I don't expect Texas to double him at all except for the usual over the top cover 1 help from Blake Gideon. Geoff Ketchum on orangebloods was speculating that Texas may line Aaron Williams on him exclusively to shut him down, but I don't think they'll bother. Besides they like Williams in the middle of the field where teams have a tougher time avoiding him.
Williams is a guy who even Colt avoids in practice, but he is a bit of a secret to the media because he doesn't have many stats. It was funny in the Baylor game where their coaches didn't do their homework and decide to attack AJ. The result was three attempts leading to 1 INT and 2 pass breakups.
