Because if you have a guy like LeSean McCoy, why would you cut him...they don't make many of those guys. But there are many Jonathan Williams out there.
Also, Rick Dennison is our offensive coordinator. Was with Shanahan for a very long time.
How is that a cliche?
Also....the Bills have a Mike Shanahan-like offensive scheme. You know- the offensive scheme where any running back looks decently competent in. No one should lose sleep over this.
