Not much to add that hasn't already been said, so I'll focus on the title "Be careful what you wish for" . . .
1) All Jet fans knew we needed a better option opposite Revis. I don't know what REALISTIC alternative would have been better than Cromartie. You can quote stats all you want, but the fact is he's never played opposite a stud like Revis, and his best year of production came when he was in an attacking style of defense like the Jets employ. He may not be "shutdown", but you'd be hard-pressed to say he's not a legit #1 CB. Will he pan out? Time will tell. But we DEFINITELY got "what we wished for" and don't see how the Jets could have played that one any better.
2) Will Rhodes be a mistake? Possibly. I don't know too many Jet fans who are HAPPY to see him go, but if the CS doesn't feel he's the "right guy", at least we got an above-average replacement (IF he stays healthy), additional draft picks, and some cap-room for the players we DO want to build around. If you're honest, you'd agree Jet fans aren't doing cartwheels over this one, but rather trusting the FO to turn it into a positive move.
3) LT is a bad pickup if Greene goes down, but a better COMPLIMENT to Greene if he stays healthy. I don't think the FO can go in EXPECTING things to go wrong. They signed the player who brings an added dimension to the offense, and if things don't go according to plan, they'll have to improvise -- like EVERY FO. But the attention people are giving a BACKUP RB is really getting ridiculous.
4) Unlike the Pats, who are mostly entrenched in their system, the Jets had a rookie QB, a rookie coach, MAJOR players injured (Jenks/Leon) . . . the argument could be made that they will be better BY DEFAULT, nevermind the additions that have been/will be made in the offseason.
Tried to give a legitimate response to a (hopefully) legitimate thread. This upcoming season should be a fun one. You guys have the experience (which can't be understated) . . . hopefully we have the hunger to get there.
