And the last 3 years, the Packers have won 13 games each season. Oh, and Aaron Rodgers won back-to-back MVPs.
Sure, losing an All Pro receiver doesn't feel great, but wide receivers don't make quarterbacks look good - it's the other way around.
Look at what Jordy Nelson did after leaving the Packers. And Greg Jennings. And Randall Cobb.
Those were very talented receivers, and Rodgers made them great.
Rodgers isn't the only Packers quarterback who did this, either.
When Brett Favre lost Sterling Sharpe, did he suddenly fold into a mediocre QB?
When Robert Brooks went down, was he terrible?
