They actually need both, but they could bypass the DT and go for Adam
Carriker. He's one of the few players that physically measures up to
his stats and he's a beast at DE. He can play between the tackle and
guard and straight off the end. He's quick and according to Fox's NFL
Draft report, lost in the hype of the more notable DE's. Here's some
of the comments from Fox and Draft Daddy.

Fox:
Three Senior Bowl players that'll likely be drafted after the first
round, but will be outstanding...

1) Auburn OG Ben Grubbs. He's playing his way into the first round.
This isn't a great year for guards, but he's turning into a must-have
player. He'll be a top run blocker. 2) Nebraska DE Adam Carriker.
Possibly lost in the shuffle among the top end prospects, he played
like a first-rounder all week in Mobile, but might be one of the top
10-picks of the second round. 3) Cal DT Brandon Mebane. He's just a
football player. In a lousy year for defensive tackles, someone will
fall in love with him and do whatever it takes to get him in the
second round. He's been great this week at getting into the backfield.
