There have been doubts about whether Josh Allen can become one of the best quarterbacks in the NFL and Sean McDermott is aware of the sentiment.

McDermott said that Allen's continued development is "at the top of the list" of things that the Buffalo Bills need this season.

"Well, I think that's understandable," the coach said of doubts. "Until you're able to silence that, it's going to continue to come up. I think at the end of the day Josh wants to prove himself inside the building first and I think he continues to do that and show his teammates who he is and what he's capable of."
