Just laying out a scenario.
Aaron Smith is out. Troy is out. The Browns best aspect of their team is the O-Line. They pull what Detroit did the second half the whole game, control the ball eat clock wear down a no longer deep D-Line. Exploit the rookies when they have to play and keep Ben and the offense out of rhythm.
This would give them a very good chance of pulling the upset. if we can't get things going on offense and let's say Ben gets a pick six, or Rodgers blocks a kick and they return it, or Cribbs get a big one, they can win this game.
With Aaron and Troy, this game is laughable. Without them this is the weakest defense we've put out in a long long time. Sonny and Ziggy aren't ready to stuff a determined running game, and Jamal Lewis is smart enough to make the most of it. Besides he always runs well against us.
