Scheme can only do so much (not that Fisher's scheme did much of anything at all). Ultimately you create space for yourself with strength, quickness, and crisp route running.
We've just spent so long making excuses for Tavon that I can't do it anymore. Remember when Foles came aboard? There was talk of how, since he's taller, he'll have a better view over the OL and he'll be able to see Tavon...as if that was the one thing holding him back.
I mean, yeesh. At this point if he just puts up serviceable numbers for a year before we cut him, I'll be a happy camper.
