Almost always happens in the same game the offensive line cannot protect Brady. Chicken or egg...do they struggle to protect because the other team knows they can't run against a base defense, or do they not run the ball well because the offensive line sucks/the passing game fails to establish its needed dominance to establish their running game.
Either way, I somewhat agree that I'd like to see a more consistently good running attack in the postseason, but frankly I'm not sure if many teams can really do that. It seems like you face better run defenses because holes just don't seem to open up. That has not just been a Blount issue; it has been an issue for the team for a long time, which is why they seem to have favored the short passing game (utilizing running backs like Vereen and White) rather that trying to establish the classic running game.
