CORVALLIS -- Ryan Nall is still learning how to run.
Or, at least, learning when to stop running.
Coaches tasked Nall with studying himself on film this offseason, not to gloat about the defenders he dragged while gaining extra yardage for Oregon State but to become cognizant of the way they can pull on his ankles or drape themselves across his back.
The Beavers hope that increased awareness, combined with other preventive tactics, will increase Nall's durability -- perhaps the only knock on the ballcarrier with the unique combination of size, strength and elusiveness that make him an all-Pac-12 contender in 2017.
