It’s clear that Rex Ryan did some serious self-scouting during the Buffalo Bills’ bye week. On Monday, the coach announced that there would be an open competition for several starting jobs.

Entering Week 11 with a 4-5 record, Ryan was blunt in his press conference on Wednesday.

“I’m tired of mistakes. I’m not here to make friends, man,” said Ryan. “I’m here to win.”

Coach Ryan is well-known for talking a big game when addressing the media, but right now, it’s clear that he means business.

Second-year cornerback Ronald Darby was benched in the team’s Week 9 loss to the Seattle Seahawks and Corey White was given first-team reps in Monday’s practice.

On Tuesday, Buffalo signed veteran safety James Ihedigbo and released Duke Williams, who was in the final year of his rookie contract. Additionally, Ryan called out right tackle Jordan Mills, who’s struggled mightily in recent weeks, while praising Seantrel Henderson’s progress and said that he wanted to give him an opportunity.

If that wasn’t enough, on Wednesday, he opened up a competition for the slot cornerback position, stating that rookie sixth-round draft pick Kevon Seymour would have a chance to unseat Nickell Robey-Coleman for the job.

The Bills’ defense has been atrocious as of late, surrendering 1,087 total yards and allowing 100 points, which has resulted in the team’s three-game losing streak.

Tensions are high in Buffalo and with the playoffs looking more and more out of reach, coach Ryan is putting the entire team on notice as they prepare for their final seven-game stretch.
