Different circumstances. Brady under contract already and the deal pretty much had to get done to make other moves. These guys are free agents and, at best, the numbers are being negotiated. We also don’t know the “real” interest from both sides.
There’s little reason to sign anybody else before training camp, Suh probably wants another 10m we don’t have, AB needs to keep out of trouble and is going to pass a lot of guard shacks on a bike most likely, and fournette is RB of a dime a dozen caliber.
