Jackson was a late second round pick who took years to develop, and he had a pro-bowl QB putting the ball right *there* for him. It will be interesting to see how he does without that.
Edwards is just as fast and has a better character. He will also work his ass off to succeed. I will be as surprised if he doesn't become a solid NFL receiver as I will to see Jackson put up pro-bowl numbers with someone like Matt Leinart throwing him the ball.
Unfortunately your average football fan has no patience and wants the all important instant gratification just like the average person wants out of everything in life these days.
