DeadHorse, you listed Felix Jones twice. I'd also argue with a whole bunch of guys on your list.
Regardless, Cedric was a hugely productive college running back. If you're going to use "stats" to make your argument, then you can't dismiss the giant stat people keep throwing in your face: #6 all-time.
True, he played as a freshman so he had almost 4 full years to rack up those yards. True, he benefitted GREATLY from the zone read and Vince Young. But, he also had some fairly significant injuries he had to fight through.
Ultimately, I wouldn't put him in the top 10 all-time best college running backs. I might see him at the bottom of the top 20. To your point, he seemed to have a difficult time "making his own way", which all BUT the very best seem to struggle with. Ergo, he's not one of the very best. Ricky Williams could make something out of nothing on a consistent basis. Not all the time, but probably half the time. Cedric, not so much.
What an egocentric dumbass he is.
