Message: [QUOTE="blizz, post: 2298560, member: 4252"] My understanding is that they call the protection. Makes sense if you think about it, trying to go as fast as possible, the play call will usually determine the line assignments from a scheme perspective so the read will simply be the number of the front and the number in the box. Having the running back call this out and then set the protection frees up the qb to read the back 7 while that's happening. Might not seem like a big deal but when you're trying to go from snapping the ball every 30 seconds to every 20, that can be the difference. [/QUOTE]
