HB
There's 29, count them, 29 HBs you could potentially draft but only 14 almost always get drafted. Aside from speed, the easiest philosophy to draft for is Moves, the hardest being Receiving.
Darren McFadden is quite easily the best HB in the draft. He has the highest potential for ALL 6 HB philosophies. You have to get him super early, like top 5 pick early.
There's 4 busts in this one, based on average potential. Chris Johnson, usually a 1st round pick, is 90 POT as a Moves HB and 91 as a Speed HB (but you should never use the Speed philosophy for a HB OR a WR). Any other philosophy and he's a bust. Jonathan Stewart, outside of Speed HB, is a bust in all the philosophies. Matt Forte is a bust in ANY philosophy (even Speed LOL). Kevin Smith can usually be pretty good ut his average POT is 84. He's 85 in the Moves philosophy and 86 in the Workhorse and Power philosophy. His learning rating is pathetic though and you'd have to use a 2nd round pick on him.
Aside from McFadden, there's some other serviceable HBs available. You could get Rashard Mendenhall (averge POT 89) or Felix Jones (AVG POT 91) but you'd have to get them in the 1st round.
Ray Rice is a steal in the late 2nd round/early 3rd round. His AVG POT is 87, 91 as a Power HB. For a solid Moves HB there's Jamaal Charles in the 3rd round. He needs a lot of time to develop though. Slaton sucks, don't get him.
3 more steals you can get very late are Mike Hart, Xavier Omon, and Jamaal Buckingham. I've seen Hart go early in the 5th and as low as late into the 6th round. His AVG POT is 84 but I usually go after Omon and/or Buckingham. I play as the Raiders usually and instead of getting McFadden, I draft Omon and Buckingham as a one-two combo. Omon either goes midway into the 7th round OR he might go undrafted and Buckingham pretty much ALWAYS goes UNDRAFTED. Omon has 88 AVG POT, 91 as a Workhorse or Power HB. Buckingham has 84 AVG POT, 90 as a Workhorse or Power HB. Both are great power HBs that do pretty good early on (especially Omon)
So with all these HBs, Darren McFadden, Ray Rice, Mike Hart, Xavier Omon, and Jamaal Buckingham are the only HBs I'd ever draft. Wow.
