I thought the analysis was definitely pro Peterman biased, but the summary at the end was spot on.
"I don’t think the Bills have an exceptional talent in Peterman (although if his arm strength were to improve, I might be inclined to re-evaluate). But he’s smart, poised, and can pick apart a defense..... But outside of leading this team to the playoffs as a rookie, nothing he does this year should preclude the team using a first round pick on the position in 2018."
