Article About the Evolution of the Shanahan System and What Makes it Work

How about Lynn Bowden being that wide receiver coming out of the backfield?

That's a good point. Someone recently pointed out that he won an award in college for the most versatile player the year that he ran for a bunch of yards as a QB at Kentucky. And we know he can block and has YAC ability so he would seem to be a good bet to at least approximate the Deebo role. He's probably not going to be the player Deebo is, but he can be used to create the illusions of formation so important to the Shanahan system.
