Its obvious that when a team blitzes, there are likely going to be defenders unaccounted for by the offense's blocking scheme.
But that has nothing to do with "missed blocks".
And Manhertz's "missed block" on the man that he obviously chose to attempt to block had nothing to do with the blitz.
Preseason story so far was to narrow it down to 53 man roster, lots of guys on the fence getting extra playing time to show their stuff. So last game of preseason will be just the players who made the team?
