Thanks K-9. That was an excellent and informative read. I now understand what you have been saying about Cooper's game against the Chiefs. He was instrumental on at least three plays of needing to be bailed out by others in order to keep the QB upright. On one of those occasions, no help was available and the QB suffered a severe hit. I still believe that Cooper will be just fine, and another game or two might just settle him into where he needs to be. The game speed is very different than practice speed is.
I am very impressed with the author's insight, especially into the techniques involved for playing running back at this level. He has made very clear distinctions of the differences between backs such as Ellington and Williams, versus types like Grice and Taylor. He is also an excellent author, being able to not just see those differences, but to communicate them to the lay man. Nice find K-9.
