that is the point...a defense can shut a WR down. Rodgers elevates all of the WRs on his team because he is so great.
here are some of CJ's yardage totals in his games last year.
37 - win
44 - win
25 - win
83 - win
52 - loss
43 - loss
A wr can have a bad game or not be involved in the offense and the team can still win. QBs are just way more important to the offense than ANY wide receiver. Hell, even Stafford is more important to the Lions offense than CJ.
Just because a WR doesn't put up big numbers doesn't mean he didn't have a good game. A guy like Calvin neutralizes their best CB and most likely a safety. You are essentially playing 10 on 9 even if CJ doesn't touch the ball.
A QB should be the most important player, but on our team it's CJ.
