"Buffalo Bills coach Chan Gailey was decisive Monday in announcing quarterback Ryan Fitzpatrick would assume the starting duties from Trent Edwards.

When it comes to who will start at running back, however, not so much.

Gailey was noncommittal when asked if Marshawn Lynch would remain in the starting role he filled Sunday at Green Bay.

"It depends on the package," Gailey said. "That all depends on the packages that we deal with. We're trying to develop packages for each of our guys and it depends on which packages we go with."

Lynch got 17 carries against the Packers and gained 64 yards, an average of 3.8 yards per rush. Rookie first-round draft pick C.J. Spiller, who started the season opener against Miami, got just one carry in Green Bay, for 3 yards.

The only back not to begin a game so far this season is last year's starter, Fred Jackson. He rushed nine times against the Packers for 39 yards (4.3 yards per rush) and a touchdown, the team's only one on the ground so far this season.

Gailey said keeping fresh legs in the lineup will continue to be a priority.

"When you have three quality backs you try to keep a fresh guy on the field at all times," the coach said.

It hasn't mattered who is in the backfield for the Bills so far in their 0-2 start. The team is 23rd in the league in rushing, averaging 87 yards per game. Lynch leads the team with 20 carries for 77 yards, while Jackson has gained 58 yards on 13 carries. Spiller has averaged a paltry 1.1 yards per rush, with just 9 yards on eight rushes.

"We're not playing the way we should be and it's a matter of cleaning that up and coming out on game day and getting it done like we've been getting it done in practice," left guard Andy Levitre said."
