Vinatieri was Mr. Clutch, while Longwell was Mr. Choke (he even missed a PAT)
Baltimore's D is questionable, they unloaded lots of starters; NO gave up a ton of points last year, yet they had many sacks and a good amount of TOs.
Pittman has durability concerns, and Alstott will steal goal-line opportunities from him anyway. Stewart has been a non-factor and Taylor gets hurt a lot.
You might want to unload Emmitt for another quality WR. Booker's production will fall due to Marcus Robinson's return and emergence of Dez White and David Terrell. Besides the fact that the A-Train will carry the load. Your other WRs are pretty solid.
With the small amount of teams in your league, your waiver wire should be filled with sleepers and known-good players.
