This.
With the new rookie signing agreement I don't think a rookie can sign for longer than four years with a fifth year option, don't quote me on this though.
Granted you would expect to have aleast one or two "solid players" from those years still on the team, guys who have been core players and helped your team win.
Reese has failed to get players who have been able to be a core part of any successful team really, now there are circumstances such as injury hurting a lot of these first round picks, Nicks, Wilson, JPP (although it was his own fault)
I'd assume if any of those guys were able to stay healthy they would still be on the team.
