BEREA, Ohio (AP) — Browns quarterback Johnny Manziel says he “made some rookie” mistakes during the offseason and vowed to be focused on just football in the future.

Speaking on the eve of Cleveland’s first training camp practice, Manziel briefly addressed his behavior during the offseason when photos of him partying around the country were a weekly occurrence. Manziel said he has spoken to Browns coach Mike Pettine and general manager Ray Farmer and “we’ve been on the same page.” Manziel said he spoke them about a photo of him holding a rolled up $20 bill, but he provided no other details.

Manziel said he wants to represent the Browns in a “positive manner and a positive light.”

The former college star enters his first camp as Cleveland’s No. 2 quarterback behind Brian Hoyer.
