I believe Brown would be the second back taken were it just depends on team needs. Now me personaly I would take Brown over Bush, now I am going to get flamed for that. The reason being is a veiw Bush a poor mans virson of Barry Sanders. And while Barry was an awsome back he is not the type of RB that will lead u to a Superbowl. I watch Barry so many times, he put up great #'s all game and Det would be up by 7-10 points, then Fourth Quarter time. And Barry can't move the chains to get the tough first to run down the clock. There are many backs I would take over Bary. I would say Payton was the best I ever saw play he always closed out the game he was just so tough in the fourth. I see bush the same way he will put up good #'s but can't carry an Offence. Its like this Bush will not get yards cositantly so your offence is allways haveing 2nd and 3rd and long cause drives to stall, but will have good overall #'s because he ran one good run for 80 yards but that was the only drive he helped lead to a TD. While Brown get yards consitintly making it easier for the rest of the Offence to score as well.
Anyway I hope that makes sence.
