PITTSFORD, N.Y. — Corey Coleman's been with the Bills just over a week, but will be back in Cleveland Friday, facing his former team in his debut with his new one.

"There's always something to prove when you step on the field. This team has high expectations for me and also I have them for myself, so every time I'm out there I'm going to give 100 percent and do my job,” he said.

Coleman's biggest job has been learning the playbook, something he admits is hard. Overtime's been double-duty between studying and trying to get a feel of his new quarterbacks as quickly as possible.

"Just really practicing. Extra reps and such. I know a couple days we stayed after practice, throwing me the ball and getting a feel. It's going to take time to build that chemistry and stuff like that, but they're doing a good job of helping me. At night time, going over plays with Nate and stuff. He's helping me out. Spending extra time. I can call any of them. They're going to do a good job trying to help me as much as they can,” said Coleman.

And Coleman's also finding help amongst his fellow wide receivers.

"Coming here, they have older guys in the room. I consider myself an older guy, but we got guys that have been in the league, they're 30 years old. Two receivers — 30 years old. Where do you find that? So they have a lot of knowledge about football and different situations. Being traded, being cut. So there's guys that you can talk to that understand because they've been through the same thing,” he said.

Coleman says he doesn't know exactly how much he'll play against the Browns, but the coaching staff does have a plan in place. To this point, he's seen most of his time with the second and third units in practice. As for his expectation for the reception he'll receive in Cleveland, Coleman simply said, "I'm not worried about that."
