I was somewhat convinced that Sean Lewis is holding things back from the playbook, but then I watched various game films and he has an incredibly vanilla running game philosophy. His passing game stuff is next level, especially when you have a QB as good as Shedeur running it, but his offenses have relied on running QB's, better OLs, and RBs that can make something out of nothing, mainly on shotgun RPO draws.
Coach Lewis is a talented and bright guy, but it seems that his running game design, and execution is honestly, substandard by any metric.
His QB is in Shotgun 100% of the time, no under center, and no pistol
He runs about 80% straight RPO Shotgun draws, and it gets stood up a lot. By running that play over and over, he also brings most of the defense into the box and thus whether he runs it, or the QB is gonna throw, there is a lot of defensive traffic in the middle.
We are 3-0, it has worked enough, but beyond Shedeur making magical plays, his running game is meh
