"We're very, very pleased with (Manuel's) development," Marrone said. "I think that a lot of times at that position you're going to look for a lot of things and expect it to happen overnight, and it's not."
Perhaps most important: Manuel got the snaps. Marrone liked how Manuel recovered after his early struggles. Every day that Kolb misses, the more likely it is that Manuel opens the season as the Bills' starting quarterback. Manuel has looked good in hurry-up drives and impressed more than Kolb overall in camp.
We opened Bills training camp saying the tie would go to the rookie here. Manuel appears to be doing his part.
