I know you were just copying the blog title, but there was nothing in that article that said we wouldn't draft a corner in #29 as well.
The Tannenbaum quote said that without Cromartie, that we would have NEEDED to draft a Cornerback at #29. But, since they pulled that trade, they now have flexibility and they can address any position they please. That could still be another cornerback (Albeit that seems a bit unlikely, but he didn't rule it out).
i don't see the jets using their first round pick on a safety however a corner is a possibility mainly because it's far earsier to convert a corner to safety than vice versa. the jets can always use depth and they will need some players on the oline to take over for faneca and woody and then on dline for ellis. so the 29 pick may go dline or oline.
Its good that we made the Cromartie trade, hes better than any CB we would have got with that pick. Joe Haden and Kyle Wilson both in all likely hood will not be on the board at #29. Some guys with potential we could grab later, like a Kareem Jackson. But he wouldn't be someone you want starting day 1. Now we can get after a CB for depth instead of needing that starter opposite of Revis.
I fully expect the Jets to draft DL and OL early, along with WR. I think they address getting some youth to the trenches and we need a 3rd WR.
