Orchard Park, NY (AP)— Upon introducing Chan Gailey as the Buffalo Bills new head coach, general manager Buddy Nix had a momentary memory lapse.

“This is the 15th head coach,” Nix said, before pausing.

“Is that right?” he added, looking to a Bills official to ensure his count was correct. “I thought there were more than that.”

No, it just seems that way in Buffalo.

Hired on Tuesday, Gailey becomes the 15th coach in the franchise’s 51-year history, but more notably fifth in 10 years.
