For much longer than I've been covering the National Football League we've been told that the NFL is a copycat league. Some coaches may not be so blunt about it, but everyone is willing to pillage and cherry pick the best ideas from opposing coaching staffs, and what we've seen a whole lot of around the league over the last two seasons has been teams willing to take the 'Tush Push,' popularized by the Philadelphia Eagles, and come up with their own version.
The adaptation du jour this season has been having a bigger-bodied player take the under center snap as opposed to the quarterback.
