Guard in the second round, absolutely.
Guard with a top 15 pick, no way. A pass rusher, WR, or running back (if there is one) is just sooooo much more valuable than a guard. Trade back in the first, take a guard with a late 1, I can see that.
Jets #1 problem on D, not being able to rush the passer. That is the only thing on D they should address in the first 2 rounds.
Jets #1 problem on O, no speed, no ability to make a big play. That is the only thing they should take in the first round IMO. Maybe a stud RT. But the O is too slow, and that has to be addressed for Sanchez or anyone future QB. Especially since Holmes will probably be gone after next year, get in another big WR to groom with Hill and Kerly.
