The Bills signed a former starting quarterback this offseason, and then used a first-round pick on another.
But the guy who took the first snap in OTAs was the guy who was there already.
Coaches will often give incumbents the courtesy of the early snaps, but Jackson staying in that spot for long would be an upset.
Kolb looks like a sufficient bridge quarterback until they get Manuel ready. Although, to be honest, Jackson has been every bit as acceptable in his career as Kolb.
But the rookie from Florida State is obviously the one they want in that spot eventually, and the sooner, the better for a team that has lacked an identity at that position for a generation.
