In a high-powered offense like Oklahoma State, there can be a lot of running, cutting, juking that can wear on the skill players in particular. The running backs and wide receiver position account for a lot of the sprinting and cutting, which means developed depth at these positions is crucial to keep guys on the field fresh.
Last season, the Cowboys ran a play every 24 seconds, which was the slowest year on a per-play basis since 2010.
The good news is that they have all the tools to provide a balanced attack on offense, which should allow them to speed things up a bit.
