Don't know if anything about this has been posted, but it's from an ESPN piece on Matt Ryan. I didn't read the whole thing, but the part about Kyle Shanahan's offense caught my attention:
"By his own account, Ryan was enamored with Shanahan's offense; he says he never lost faith in it. And perhaps for good reason. Shanahan's mentors have included Jon Gruden, Gary Kubiak and, of course, his father, Mike. The foundation of both Shanahans' schemes is an outside-zone running game, drilled into the players until it can be run like clockwork. And so it was that Ryan was engaging with a system that, almost genetically, had its roots with a Broncos team coached by Mike Shanahan 20 years earlier and led by a quarterback who had also experienced years of heartbreak before winning multiple titles: John Elway."
Granted, Dennison hasn't called the bulk of his own plays, and we don't have a HOF or even top 10 QB on the team, but aside from Gruden, those are the same mentors. It'll be interesting to see what Dennison's offense ultimately looks like.
