I don't know how much stock I put in Blaylock's YPC being higher than Priest's, considering that Blaylock gets most of his carries either
- when he is coming in in relief and can go full-out for two or three plays, or
- in blowouts where the other team is already pretty much demoralized (like the ATL game).
These are the best possible situations for a high YPC. Priest runs in pretty much every situation, and also gets a lot of goal-line/short yardage work which brings the YPC down. While Priest may not be the best back at any one facet of the game (except maybe setting up blocks), I think in terms of total package there are only a few guys that are close...LT and maybe Shaun Alexander are there, Marshall was there in his prime, Jamal Lewis isn't a very good reciever, Edge is horrible in short-yardage, Portis doesn't even know that people are trying to block for him, Tiki Barber hasn't put a whole year together yet, McAllister isn't durable and has yet to be anything but the best player on a bad team, and Ahman Green fumbles too much. While Priest would certainly not produce as much in another system, I think that other RBs who would produce as much as Priest in his system (which I admit is perfectly suited to his style) are few and far between.
Before you take anything I say too seriously, be aware of the fact that Derrick Mason, Cadillac Williams, Reuben Droughns, Jason Witten, and Mike Bell are all on my team this year!
