BLITZ PICKUP IS PART OF THE BLOCKING SCHEME.
Should he not trust that Gandy, or Villarial, or Fowler, or Peters, or Reyes are going to pick up their blockers? Because, jeez, that's not going to happen all the time?
Good lord, man. If he can't rely on Willis to pick up the blitz, it's Willis' fault. Simple as that. Crowd noise be damned.
