That'd certainly be an odd selection.....the only way it'd really make sense is if BB and Co. were convinced that this guy was such a stud they just had to have him, no matter what.
The whole rotation idea isn't bad, except for the fact that we already have plenty of depth up front w/ Green, who has held up admirably at the NT spot in the past when needed. Also, if worst came to worst, Warren is strong enough to play the NT spot.
To me it would seem kind of silly to trade up in order to pick a D-lineman, since the D-line is by far our stongest unit at the moment, not to mention one of our youngest.
