There has been plenty of turnover among starting quarterbacks this season, meaning guys ranging from Mark Brunell and Brad Johnson to Ryan Fitzpatrick and Mike McMahon have been snagged up to fill out rosters. However, while many of these guys are there to fill fantasy bench spots for the most part, the real winners or losers in these moves are the stud receivers who have to figure out quickly if they mesh with a new signal caller.

And the effects can be quite telling. Earlier in the year, you could see how comfortable Santana Moss was with Brunell, enhancing both of their fantasy values. On the other hand, the revolving door of Jets quarterbacks meant you couldn't rely on Laveranues Coles or Justin McCareins for big stats. However, Fitzpatrick showed (at least for one game) that guys like Torry Holt and Isaac Bruce can produce no matter who's at quarterback.

This week's Dolphins-Bills game showed a couple of interesting variations on that theme as Miami's Sage Rosenfels found Chris Chambers as often as he could after replacing the injured Gus Frerotte. In some cases, backup QBs find their fellow reserve receivers when pressed into action. But with the Dolphins staging a furious comeback, Rosenfels went to the sure thing -- and Chambers responded with a couple of team records.

On the other hand, the Bills seemed to have figured out who their No. 1 receiver is as Lee Evans caught three first-quarter TD passes from J.P. Losman in that same game. The fellow second-year players have developed a rapport in the passing game, leaving veteran wideout Eric Moulds in the dust (he was held without a catch). And with Losman in place the rest of the season, it appears Evans' value will increase now and into next year.

Fantasy Stud of the Week

Chris Chambers, WR, Dolphins (15 catches, 238 yards, 1 TD): Just two weeks ago, Chambers was held to just three catches for 12 yards. Now he has 100-yard games in consecutive weeks, including setting team records in receptions and yards this week. Chambers can be a reliable target, so that's how Sage Rosenfels turned to in leading Miami's fourth-quarter rally. His last-second touchdown was the topper on a wild fantasy-point day, although his value depends on your league's rules. The one touchdown is OK for TD-only leagues. The 238 yards are great in yardage leagues. And the 15 catches are huge in point-per-reception leagues.

Fantasy Dud of the Week

Eric Moulds, WR, Bills (0 catches, 0 yards): With J.P. Losman likely the starting quarterback the rest of the way, it may be best to keep Moulds on the bench. Losman has found a groove with fellow 2004 first-rounder Lee Evans, finding him for three touchdowns in the first quarter, while Moulds was shut out. Moulds operated well with veteran Kelly Holcomb, but Evans is the guy with Losman.

Waiver Wire Wonder of the Week

Sage Rosenfels, QB, Dolphins (22-37, 272 yards, 2 TDs, 1 INT; 2 carries, 5 yards): With Gus Frerotte knocked out of the game with a concussion, Rosenfels fired two fourth-quarter touchdowns, including the game-winner to Chris Chambers with six seconds left. While the running game is Miami's strength, the passing game showed some life, although who knows how long that will last.
