Perhaps the strategy should be to cut Sanu in the hope that someone else out there can replace him at the same price. NOT!
Next year, we have Edelman (who could retire or be traded to play with brady) and Harry. We need at least 3 more. If BB knows a player than he can sign for $6.5M a year, he'll do it. AND, he would then EXTEND Sanu, not cut him.
We would then have 2 WR's for the same cap money, both on 2-4 contracts. AND, Belichick would still looking to add a WR or draft one.
Edelman, fa, Harry, Sanu
If BB tries to extend Sanu, Kraft should fire him.
