Clock ticking for Manuel, Fitzpatrick

Before the season even kicks off, the clock is running on two quarterbacks: the Buffalo Bills' EJ Manuel and Houston Texans' Ryan Fitzpatrick.

The Texans traded a conditional seventh-round pick for Ryan Mallett that turns into a sixth-round pick if the quarterback plays in 40 percent of Houston's offensive plays this season, a source told ESPN. And the feeling around the league is that it will not be long before Mallett gets his starting opportunity in Houston and that the conditional draft pick traded to New England turns out to be a sixth.

Meanwhile in Buffalo, even some within the Bills organization have reservations about whether Manuel is going to be able to succeed. Buffalo, per one league source, is "not afraid to pull the trigger" on a quarterback change and turn to recently signed Kyle Orton.
