The question at the end of this season may well be: why were either of them starting ahead of Brandon Jacobs?
As one of the few Auburn fans on this board, I'll take a shot at this answer. During Brandon's one year at AU, the backfield was ridiculously crowded with Caddy, Ronnie, Brandon, and Trey. Trey never did anything else, but at the start of the 03 season, he was coming off of a huge game against Alabama at the end of the 02 season and people were high on him. There weren't enough carries to go around. Add to this, that Brandon couldn't catch, pick up a blitz, or give a damn while on the practice field only added to him getting pushed down the depth chart.I've watched a lot more games with Ronnie and Caddy than most the board, and I realize comparing SEC to NFL is pretty pointless, but Ronnie has always been the better more complete back. Why did Caddy start? Ronnie was terrible his RS freshman year (01), and didn't come into his own until getting a chance half way through 02. Additionally, Caddy was a pretty strong Tennessee lean for most of his recruiting, until Tuberville made a last ditch recruiting visit to Carnell's house, and PROMISED him immediate playing time and the starting position. This wasn't that hard to promise going into the 01 season, as Rudi Johnson had left in 00 and there was open competition for the job. Then Williams went out and proved he deserved the starting job over Brown during the 01 season. He was named the starter and never did anything to lose that job. Then during the 02 season, he was injured and Ronnie showed his worth. Coming in the the 03 season, Auburn had the crowded backfield and a terrible offensive coordinator, as Bobby Petrino had left after one season in 02. The entire 03 season was a bust, but both backs still produced. Again Cadillac never did anything to lose the job. 04 brought in a new OC, who was able to use both backs properly. Basically my longwinded blurb is saying Cadillac never did anything to lose the job, after claiming it during the 01 season, and that's why he was the starter.
