We saw this with the ’07 Patriots toward the end of the year (especially in the Super Bowl) and it looks like we’re seeing it with the Packers this year. Sure, it’s halfway through their 3rd game as I’m typing this and they’ve played two very good defenses (Seattle/San Fran), but the game plans are very obvious. Rush 3-4 guys, drop everyone else in pass coverage. The Packers’ offensive line is so bad, that you don’t even need elite pass rushers to get sacks. Rodgers can keep trying 1-4 yard passes, but he’ll get sacked and people will drop passes, and points won’t get scored.
There will be opponents that are determined to play their own schemes (ie – blitzing a lot) and they’ll lose as a result. But the smart teams will follow the Seattle blueprint and will largely find success.
