In any reasonably healthy fanbase, there will be some disagreement about how good the coaching staff is. There are a fair number of Falcons fans who are convinced that Dan Quinn is not actually a great coach so much as he is a shrewd evaluator of talent, and plenty more who think he is a great coach with some clock management flaws that show up a bit too often.
Regardless, I think we’d all agree that the Falcons have some good coaches on staff, even if you’re sour on Steve Sarkisian. I think at minimum I’d put them in the top half of the league, and probably toward the back end of the top ten if Sark has made any strides at all.
