The Offensive starter for the Bills to watch during Saturday’s preseason game against the Steelers is Matt Cassel. The QB competition is still a three horse race with Rex Ryan indicating that all three of them will get time with the first unit. Cassel is still the leader with Tyrod Taylor on his heels and EJ Manuel in third place. Cassel didn’t play last week as the coaching staff wanted an extended look at Taylor and Manuel. All that did was bunch things up even more.
