You don't draft guards number 9 overall. You just don't. If they trade back, maybe. I don't see them drafting a RB before round 3 either. Other holes to fill.
If it's me, I trade back this year, then start the rebuild of the offense from the interior out, assuming trading back means we will have 3 picks before RD. 2 is over, I try, and come away with a run maulling OG, and a pass protecting OT, and then depending on the offense my new coordinator is going to run I either grab a POTENTIAL 3 down RB, or a stretch the field speedster at WR. Again like I have been saying I fix those problems 1st, and try to tank 2013 season, and go get my QB in the 2014 NFL draft, and let the QB come here with a nice offensive core already devolping, and just waiting for him to take the keys, and drive.
IF you trade back this year, and trade Revis for a 2014 1st, AND a 2nd in this years, or next years draft, that gives you a minimum of 6 draft picks in the 1st 2 rounds of the next 2 drafts, 4 should be spent on 2 OL, 1 RB, and 1 WR, 1 on a QB in the 1st round of the 2014 draft, and the last spent on either Revis' replacement, or a OLB/DE pass rusher, which ever one you don't get you use your cap wisely, and save $$$$$$ to plug that hole.
IMO the above is a great plan to have the Jets playing exciting football in 2014, and competing no latter than 2015, and maybe 2014 if the QB you draft happens to be as good as Luck, Wilson, or RGIII, and you made all of the correct decisions with other personnel from now until the start of the 2014 season, obviously this plan is contingent on not missing on more than 1, or 2 of those 6 picks minimum, that really shouldn't be that difficult either with the right guy, it is not hard to pick the safe OL pick most smart GM's get those right, and RB that high is usually a safe pick with the smart GM in the 1st, or 2nd (probably 2nd round), the hard positions are pass rusher, CB, and the most difficult, and important QB.
Also with this plan, my goal would be to execute the moves to setup my next 2 drafts like this, Trading Revis would net me a 1st in the 2014 draft, a 2nd in the 2013 draft, my trade back depending on how far I move will cost either a 2nd in the 2013 draft, or if it is a huge move a 1st in the 2014 draft, also both would net us the trading teams 1st rounder. So after all the moves are made our next 2 drafts would look something like this.......
2013 1st round (1 late round pick)
2013 2nd round (3 total picks) 1 from the Revis trade, and 1 from the move back.
2014 1st round (2 total picks, if I worked my plan right, and tanked the 2013 season 1 very high pick, preferably top 2, and 1 other pick TBD slot) extra 1st round pick from Revis trade.
2014 2nd round (1 pick, possibly 2 if I was able to completly fleece the team I traded Revis to, I would try and accomplish this by asking for a conditional 4th rounder for the 2014 draft, that could reach as high as a 2nd if X is reached)
That is 7 total picks, possibly 8 in those 1st 2 rounds of the next 2 drafts, and If the Jets somehow over achieve in 2013, I offer both my 1st round picks, and whatever else it takes to get my future QB in the 2014 draft if I deem the prospects to be worth it (I do believe there will be 1, probably 2 available in that draft that will be considered as PROJECTED franchise QB's by just about everyone like the 2012 draft).
