I gotta say, I'd be pretty happy with the Pats if they picked up these players. CJ Spiller's got the potential to be a real difference maker; Percy Harvin without the migraines. Picking up one of the best tight end prospects, some additional depth along the defensive line (with a player most seem to project as a first rounder), and Sapp seems to have the instincts and athleticism to be a playmaker on defense.
Really thinking that's what the Pats have been missing; someone on D that's just really, really disruptive. Mayo's a stud young LB, but he either doesn't (or hasn't been asked to) get to the QB all that often. Merriweather makes some plays, but most of the defensive backs are more solid than playmaking. Sapp's got the potential, at least, to be a Demarcus-Ware type, a guy that just makes **** happen.
