My point is he already displayed that he could play at an elite level in this league before Caldwell got there. I’m not saying coaching is completely irrelevant, but I would say Caldwell with Stafford is a lot different than, say, Waldron getting the best football out of Geno.
I would say this is another good example of coaching making a difference, imagine if the Falcons hired Shanahan instead of Quinn as HC in 2015. That would be a significant rewrite of recent football history. The Falcons failed Ryan long term by bringing in a defensive HC, even though they got close to winning it all in 2016.
