PITTSFORD, N.Y.- It is day 2 of Bills Training Camp at St. John Fisher College and again, all eyes are on the quarterbacks.

Veteran Kevin Kolb is trying to prove experience is key under center and win a starting job, while many have also said that it is rookie E.J. Manuel's job to win.

On Monday, Manuel looked smooth, completing some very impressive touch passes, including a 20 yarder to Chris Gragg and a gorgeous 50 yard near-touchdown to Robert Woods.

Kolb, on the other hand, struggled. He got caught several times in the blitz and was forced to throw a few balls out of bounds.

After practice, Coach Doug Marrone offered a bit of an explanation. Kevin Kolb is seeing a much wider array of the Bills' defensive package than is E.J. Manuel.

"I probably saw a little bit more production than I saw yesterday. A couple reads. I thought both quarterbacks had very good one-on-ones against the DBs. I think in the teams they saw something a little bit and then I saw them miss some things. I think Kevin (Kolb) is seeing more of the exotic stuff from our defense. We'll bring in EJ (Manuel) and gave him a little more reps today but we're careful with what we're showing him. EJ is in a pretty decent position. We throw Kevin out there and Kevin's going in there and seeing everything for the first time. And EJ is able to sit back there and look at it. Now we've got to start stepping him up in those situations too."

Kolb said he accepts it as part of the process. "I'm not paying attention to who gets what. It's just a learning curve for all of us. Seeing we all know what our defense brings. They bring a lot of different looks. They got us a few times today in that third-down period; got me a few times I should say. They mix it up well, so it's a lot of stuff to look at. But it helps you down the road and I'm glad I get to see it now rather than being surprised by it in the season."

Manuel says he is settling in more and more with each workout. "I feel a lot more comfortable. I understand my protections, been going over that a lot during the offseason and also now with Coach Hackett. Just going over all the playbook, I feel that I have a better grasp on (the playbook) than I did in the OTA's."
