I don't know. They are starting to show their age. I give them one or two more years before they will have to re-build. The Giants are a young team. Look for them to be a good team for the next few years.
The Patriots won't be "rebuilding" any time soon - they are the best at finding role players to plug into their system, their entire team sans Samuel and Moss are signed, they have the #7 pick in the draft, they will be fine.
If I remember right they were right on the edge of the cap. You factor in a top ten draft picks plus your other picks, theres no way they can sign both of them Samuel is going to look for Clement's 8/80 and Moss is going to want to cash in. I think first of all they need to get Moss back, but I don't know if they can afford it.
I will almost guarantee (not quite put the house on it) that Moss is back in NE next year. Something like 4 yr/$25 mil or something, with a large signing bonus that they can pay off over the life of the contract. I don't see anyone paying him much more than that especially for a problem prone WR with 11 years on his tires already. Plus, they are amazing at getting guys to buy into them as much as they buy into the player. I truly believe Moss was happy this year, and will want to stay with a good QB, and even after last night, there's stlil only one other QB on the level of Brady (no QB plays well from his back!)
Samuel I can see leaving, just with how things went down last summer.
