What ever happened to Marcus Dupree??
Football fans needs to watch this:

Yeah, he could have been the best.
But it's not just talent that gets you there.
Walker had a greater ypc in the USFL than this dude.

Could Walker have been the best ever too? Anyone that wasn't the best, could have been the best if situations were different. I don't know why people like to daydream about this stuff.
Dupree's injuries and how he got them are part of the story.
It's no daydream.
Dupree's Freshman year at OU was fantastic. Supposedly the guy hardly practiced or worked out. Put out 260+ in the bowl game, pulled a muscle or two, then he went pro.
Speaking of Walker, in the couldabeen category.... good point, his first 3 years in the USFL:

1985 USFL New Jersey Generals 18 23 37 467 1 12.6 2.1 25.9
That last season 1985 is just plain insane - forget the competition - in terms of how much he ran, for 18 games, for that many games, on the old artifical turf of the Meadowlands. The next year with the Cowboys they ran him a THIRD of that number.
In 1988 he had over 2000 total yards but besides that he was relatively little used but always produced.
