I tend to take note when a back is a lot better than the other guys on his own team (or a lot worse, for that matter). In the case of Trent Richardson, for example, he’s been terrible in his two years with the Colts, averaging down around 3 yards per carry. Some attributed that to the team’s offensive line or Richardson needing to better learn the offense – especially early in his run there. But all of the other running backs they’ve used have tended to be about a yard per carry better – Donald Brown, Ahmad Bradshaw, Boom Herron.

That kind of stat tells me that the problem isn’t the offensive line, it’s Richardson.

Anyway, this kind of thing comes up regularly, and I thought I would formalize it a little this year. Make it more comprehensive.

I started by tossing out all running backs with fewer than 50 carries. Otherwise the sample size isn’t big enough. Then I looked at each team and pulled out the guys who were at least a yard better than all of the other running backs on their team.

They are as follows (alphabetical by team).

ARIZONAAttYdsAvgLg
Kerwynn Williams532464.6419
Stepfan Taylor632083.3021
Andre Ellington2016603.2822

This will probably be obsolete when Arizona drafts Todd Gurley or Melvin Gordon next week, but Williams had a nice little run at the end of last year.

BALTIMOREAttYdsAvgLg
Justin Forsett23512665.3952
Lorenzo Taliaferro682924.2931
Bernard Pierce933663.9428

Forsett was one of the big surprises of last year, and the Ravens have re-signed him.

CAROLINAAttYdsAvgLg
Jonathan Stewart1758094.6269
DeAngelo Williams622193.5317

Stewart closed last year on a hot streak and should get a much larger workload this season. Williams now with the Steelers (and should start in September while LeVeon Bell serves his suspension.

CINCINNATIAttYdsAvgLg
Jeremy Hill22211245.0685
Giovani Bernard1686804.0589

Hill was way better as a rookie than I ever could have imagined, blowing away Bernard (who was great as a rookie in a different offense the previous year).

DALLASAttYdsAvgLg
Joseph Randle513436.7365
DeMarco Murray39218454.7151

Murray led the league in rushing last year, but a huge portion of his success can be attributed to the league’s best offensive line. Randle consistently popped runs when they plugged him in for spot duty, which I take as an indication that whoever the Cowboys start at tailback this year will post good numbers.

HOUSTONAttYdsAvgLg
Arian Foster26012464.7951
Alfred Blue1695283.1246

Blue had one big game at Cleveland, but he ain’t no Foster.

JACKSONVILLEAttYdsAvgLg
Denard Robinson1355824.3141
Toby Gerhart1013263.2323

Robinson was surprisingly good in a handful of starts (until tailing off) while Gerhart was worse than most expected – just too slow.

KANSAS CITYAttYdsAvgLg
Jamaal Charles20610335.0163
Knile Davis1344633.4648

Davis is one of the league’s best handcuff backs, but he’s simply not in Charles’ class.

MINNESOTAAttYdsAvgLg
Jerick McKinnon1135384.7655
Matt Asiata1645703.4819

Let’s see where Adrian Peterson winds up. If they move him, McKinnon could be one of the surprise running backs of 2015. He’s got great physical tools and was a lot more explosive than Asiata last year

OAKLANDAttYdsAvgLg
Latavius Murray824245.1790
Darren McFadden1555343.4525

To me, Murray looks like an ‘80s-style running back – Eric Dickerson, Herschel Walker or Marcus Dupree kind of guy. He’s a big, fast runaway train. Even if you set aside his 90-yard touchdown against Kansas City, he was still almost a yard per carry better than McFadden.

PHILADELPHIAAttYdsAvgLg
Darren Sproles573295.7749
LeSean McCoy31213194.2353

Sproles is a little stick of dynamite in that offense. He averaged under 5 yards per carry in only three games. McCoy, meanwhile, didn’t quite fit (which is why, I suppose, they shipped him off to Buffalo).
