I don't understand how guys like Austin Sanders and Coleman Thomas got knocked back on their butts by Mckenzie in drills. I know KM is a lot stronger, but don't coaches teach things like pad level and leverage to negate the opponents superior strengths? Those young men have been here going on 2 and 3 years, respectively, and should know the basics of blocking. Good grief, the Sullins twins were much smaller and they helped a running back, IIRC, gain 1200 yds.
