The thing I love about Rodgers is that he doesn't just get the ball to his receivers, he puts it in a spot where only they can get it (see Jennings TD). Also, he can get his streaking receivers the ball without them breaking their stride (see Finley's slant and Jennings 35 yd reception.
When Flynn came in, he got the ball to his receivers, but gave the defender the chance to hit the ball. I actually felt kind of bad for Flynn because there was no way he was going to look good after what A-Rod did out there.
