I am of the opinion now that the Jets will do nothing this year simply because they don't have too. I wouldn't expect them to do anything if they are losing until 2016 season when Buff and Ladd are entering the last years of their contract. If things keep going that route then I expect them to dump players and go for a short rebuild.
They could net a nice haul then with Kane,Ladd, and Buff moving on. You would have Morrissey,Ehlers,Petan,Lowry,Lipon etc.. ready to enter the lineup and you could go young with the possibility of multiple 1st rounders in 2016. You would have Wheeler,Little,Enstrom and Frolik as your Vets and basically it would become Schief/Trouba's team.
Thats if they continue the trend that were on. Maybe PoMo can turn it around. At least they probably are going to let him try for a year or so.
I think though that if you're not looking to get Ladd and Buff re-signed, you need to move them this season for prospects and/or 2015 picks.
The reasoning is if you wait until 2016, and then get the prospects or picks, those players are not going to be ready for probably 2 or 3 years (unless the prospects are just about to make the jump), and more like 4 to really contribute (for the picks anyway). That's 2020 when those picks start to contribute. Scheifele is going to be 28 by then, and it's going to be the same conversation, but replacing Ladd / Buff etc, with Scheifele.
IMO, if they are not going to re-sign Ladd and Buff, we need those prospects now, and 2015 picks at the latest (because it's such a good draft). That way, those prospects can be playing by 2015 or 2016, and the 2015 pick (depending on how low), by 2016 or 2017.
For me, Chevy needs to know which way Ladd and Buff (and they as an org) are going to go. If those two are not re-signing, the time to move them is this season IMO.
