Actually I think Shelton was a penetrating DLman who had difficulty with 2 gapping when he came here and thus were the very mixed results we saw last season. THIS season, thus far, he has been a lot better. By all apparent reports he has surpassed Pennell as the primary middle guy. Here's the thing. It looks more and more like we are going back to the 3-4 as a base defensive alignment. But that being said, I think defensive alignments are going to be a LOT more "fluid" than they have in the past. So trying to figure out roster cuts by positions is going to be more difficult this season. That's why you see good players like Wise being projected as a cut, simply because he is viewed as not being a 3-4 DE in the standard prototype of what a 3-4 DE should be (think Richard Seymour). I'm not sure if that prototype holds up with the different type of 3-4 Bill is building this season. Regardless of how Bill views his DL, I think Cowart makes the team. Too much potential to let him slip away, even though he's probably about 2 years away from reaching his potential. However if he DOES reach it, it could be awesome. Butler is the vet, who I think will be the interior guy that gets let go. He was decent as a player, especially as a UDFA, but he hasn't shown any of the burst he had they got him noticed his first 2 years. Has he even had a tackle this preseason? Pennell has been a real disappointment in the practice games. Nothing he has done has impressed. He's doing nothing against 3rd stringers. Seems odd to compare that with the guy who was dominating at TC against starters less than 2 weeks ago. Very strange development.
