The Cardinals needed this one. So did their quarterback.
Kurt Warner wasn't happy when his six-turnover showing in Week 4 raised questions from reporters about his job status. Warner silenced critics by delivering the efficient performance Arizona needed to right its season following consecutive road defeats. Warner's job was never in jeopardy and he removed any lingering doubt in this game.
Buffalo was due for a game such as this one, but that doesn't diminish the victory for Arizona. Warner attempted more than 40 passes without taking a sack, significant progress for the Cardinals heading into their home game against Dallas in Week 6.
The Cardinals' defense needed to recapture the physical, borderline violent tendencies it showed at times earlier in the season. Safety Adrian Wilson knocked Bills quarterback Trent Edwards from the game with a concussion after only three pass attempts. The Cardinals' defense tends to play with swagger when Wilson leads the way. His return from a hamstring injury came just in time.
