I would like to see a quote of Mike Riley saying that week to week the system will completley change and packages that the team is unfamiliar with will be added.
I think it's obvious who is reading into something too much.
Not week to week. He said they are borrowing things from Kiffen and Turner that they saw this offseason (e.g., installing new packages of screen plays because Alabama used short perimeter passing against MSU). Langs also specifically said that he's putting in different packages for each of the WRs based on what they do well.
It's an extraordinarily "matchup" driven way of calling an offense versus a "system" based version. Two different philosophies. That's all.
There may be a deeper issue, though, and that is what are RIley's "core plays"? What is Lang's and his offensive philosophy?
I challenge anyone to lay out what those are, and an inability to do so is troubling.
