"To be honest, I'm not happy with any of them. I would love to see EJ come on," Kelly said. "He's a great guy. He's a great leader. I've heard him to speak to the team; I've heard him speak to the receivers before they take the field. His leadership is there. Everything is there.
EJ Manuel and the rest of the Bills' quarterbacks have not yet impressed Hall of Famer Jim Kelly.
"But I have not yet seen what we all want to see. And I'm sure he feels the same way. It just hasn't happened, and hopefully that's just because of the preseason."
Kelly said the Bills' success this season will hinge on Manuel's performance.
"I'm pulling for him, and I'll continue to pull for him," Kelly said.
