Mike Vrabel - Easily the biggest BOOM
Rodney Harrison - 2nd only to Vrabel
Rosie Colvin - Neither a boom nor a bust.
Junior Seau
Stephen Neal - A great O-lineman
Mike Compton - helped to solidify the O-line in the early years
Joe Andruzzi - Another of BB's great signings
Blue = Steal/Boom
Green = Good Signing
Yellow = Decent
Red = BUST
Black = I have no opinion one way or the other
I took most of the names from the Patriots.com website. However, its NOT a complete listing. I was able to tell that immediately by the likes of Wiggins, Ashworth, Small, Charles Johnson and Bert Emanuel not being included. I don't believe they included UDFA on the Pats site, though I have included many.
I also stopped at 2007 because any 2008 FAs haven't really be around long enough for a fully evaluation.

I am sure that I missed some because Patriots.com doesn't keep track of the rosters beyond who finishes the year on it. So, I've done my best to pull it together from there and Pro-football-reference.com
