They mentioned on the radio that it could be a tell in regards to who they plan to extend and who they don't by their draft this year. IE if they take a RB early no Gibbs, TE no Laporta, safety Branch etc.
Personally I don't agree with that necessarily, the guys I mentioned that the radio brought up still have atleast 2 full seasons of team control before they get expensive so to me next draft would be the one where something like that happens.
If you do it now then by the time you plan on them filling in you're only going to get a year out of them until you have to decide to keep them or not.
