We use Witten so much against the blitz and it is why our qb efficiency is very low versus the blitz. When you blitz Brees, Sproles or Moore give the Saints a chance for chunk yardage or a score. We don't design our offense to get chunk plays from blitz. Even Murray while not the quickest guy in the world runs a low 4.4 and is very fast with a head of steam. Miles is the fastest guy we have if his hamstrings are right.
