QUARTERBACK

F | Chad Henne had his worst game as a professional. His 42.5 rating was his worst this season as were his three interceptions. Henne found himself down a field goal with nearly three minutes to play and rather than answer with heroics, he had a meltdown over three series.

RUNNING BACK

B- | Ricky Williams had his third consecutive 100-yard game. So maybe the Dolphins should understand he is a fine RB, but as a passer, he's a fine RB. Williams threw an interception that hurt Miami's efforts. Lousaka Polite continues to be a sure thing on third- or fourth-and-short. Lex Hilliard had five solid runs, and that's more than good enough when Williams is going so well.

RECEIVERS/TIGHT ENDS

C- | Brian Hartline made a nice adjustment on his TD catch from Henne and is showing flashes of connecting with the QB. TE Anthony Fasano had perhaps his best game of the season with five catches. But the good news ends there. Against a makeshift secondary, Ted Ginn Jr. had his weekly drop plus a false start penalty, and Greg Camarillo was held without a catch.

OFFENSIVE LINE

A- | Jake Long had two false start penalties and Nate Garner added one, but this unit was hardly the reason the Dolphins lost. It won the battle at the line of scrimmage on the ground (4.2 yards per carry) and in the passing game (only one sack allowed). All this proved is that sometimes the foundation is solid and the walls still collapse.

DEFENSIVE LINE

D | The Dolphins missed Jason Ferguson. The Bills averaged 5.2 yards per rush and really took measure of the line late in the game, when Miami's front seemed worn out. Tony McDaniel brought good pressure and had 1 ½ sacks, and Kendall Langford was also credited with a sack. But this group needed to dominate against a makeshift offensive line and did not.

LINEBACKERS

C | Miami's safeties should not be leading the team in tackles and yet, Yeremiah Bell had 13 and Gibril Wilson had six. That speaks poorly of Channing Crowder and Akin Ayodele and Reggie Torbor who continually took curious angles to running backs. Miami's outside linebackers brought good pressure but lost the edge of the formation far too many times.

SECONDARY

C | The Bills' game plan was to attack Miami's secondary and they were largely successful, passing for 246 yards, including a 51-yard dagger-to-the-heart touchdown from Ryan Fitzpatrick to Terrell Owens. The secondary did support the run with gusto, however. They didn't have much choice.

SPECIAL TEAMS

C | Dolphins punter Brandon Fields had a good day, Bills punter Brian Moorman had a better day. Dan Carpenter made two extra points, Rian Lindell connected on a 56-yard field goal. Bottom line was Miami's special teams neither delivered a big play nor gave one up. Nathan Jones was excellent on coverage teams.

COACHING

D | The Dolphins had 10 days to get ready for this game and this is what they deliver? Tony Sparano took responsibility and obviously the buck stops with him. But that terrible halfback pass call by Dan Henning was inexcusable considering how Miami was gashing Buffalo with its running game. And how long will the Dolphins leave their rookie corners in 1-on-1 coverage against Pro Bowl-type receivers and not expect them to get beat deep?

OVERALL

F | This was the first upset loss the Dolphins suffer under the Bill Parcells-Tony Sparano-Jeff Ireland regime, and it came at a terrible time. Nice job in the fourth quarter, guys.
