Belichick has three weeks including a bye to assess potential trades. After that, all that we an acquire are street free agents. As has been pointed out many times, this year it is the patriots that are in need. It is the patriots that are looking to find players. A player could be at almost any position. Obviously, Belichick looks for value. I think the most likely acquisition would be at running back. OG, DL, OLB, and CB are all possibilities.
