As we near the start of the season and the rosters are just starting to take place. Thinking about adding players could be kind of a bad idea since you're trying to cut players, but nonetheless picking up a player now might bode well instead of inserting a random free agent into a system to play in with less than a week to prepare.
According to thesidelineview.com these are the available free agents as of August 28th.
Key players who can help the Patriots?
Jabar Gaffney: Possession WR and former Patriot.
Devery Henderson: Very quick, stretch the field.
Steve Breaston: Underrated part of Arizona's attack, played decently in a horrible situation in KC.
Braylon Edwards: The big WR NE needs, unreliable hands, yet great ability and has something to prove.
Lawrence Vickers: Not usually a need for NE, but he's a big guy who use to be the league's best, if not, one of the best. At 6 feet, 250 pounds. He'd be a great last ditch pass blocker as well.
