I mean just about every team has a workhorse and a spell back. As for Mckinnon, we have no clue if he can stay healthy and he's 5'8. Just because he's an athlete and strong doesn't mean he can carry the load. I mean how many 5'8 workhorses are out there?? Not a whole lot. If AP is gone and we go into this season relying on McKinnon and Asiata, it could be one of the dumbest things we could do. Because if McKinnon goes down which could be very possible if he was to see 15-20 carries per game, then we're back to square one with Asiata. We would be going in blind with McKinnon, not knowing what to expect. There are a lot of 5'11-6'0 backs in this draft, go get a guy with some size that can take the pounding
This question piqued my interest and I couldn't figure out why until I realized height has no real bearing on durability for RB. In fact it could be suggested that a more diminutive back takes less of a beating.
I think the truth is that there just isn't all that big of a number of guys under 5 10 built to run the football......but here are some guys just off the top of my head:
McKinnon 5'9" 216
Maurice Jones Drew 5'8" 205
Joe Morris 5'7" 195
Darrin Nelson 5'9" 184
Barry Sanders 5'8" 203
Ray Rice 5'8"
Frank Gore 5'9"
Walter Payton Ladainian Tomlinson and Marshal Faulk were each only 5'10" and only Tomlinson out weighed McKinnon
Then I came across these articles....evidently the question has come up a lot:
http://www.pro-football-reference.com/blog/?p=489 Running backs and BMI
A weighted average using rushing yards produces an average BMI of 29.6; the top 10 rushers of all time have a BMI of 29.7. It looks pretty clear that a BMI of close to 30 is ideal for a running back. Barry Sanders is sometimes remembered as a small back, but that's really a misnomer. He was short, but he had a BMI of 30.9. Curtis Martin and Walter Payton had BMIs below the average, but most of the top RBs had BMIs over 30. Emmit Smith and LaDainian Tomlinson are the exact same height and weight (BMI of 31.7), and Earl Campbell, Shaun Alexander and Marshall Faulk -- three MVPs -- have BMIs in the thirties. Marcus Allen, Thurman Thomas, Eric Dickerson and Tiki Barber had a ton of success with BMIs in the 27.0-28.7 range, but all relied on other skills besides sheer power. And outside of Barber, all entered the league in the '80s, when everyone was a lot smaller.
The BMI formula is simply:
703 * weight/ (height^2)
Mckinnon is 31.9 the only guys in the study who were higher:
Jerome Bettis 35.1
Jamal Lewis 33.5
Ricky Williams 32.4
Earl Campbell 32.4
Jonathon Stewart 32.6

As you can see, running back used to be a tall man’s position. But average running back height has steadily decreased, dropping 1.8 inches from 1965 to 2013. At the same time, running backs are getting heavier, although players at all positions are getting heavier. Still, I thought it would be useful to calculate an average weighted weight of running backs since 1950 using the same formula:

Like most red-blooded Americans (over forty million to be exact), I camped myself in front of the television to watch the two Championship games last Sunday. Amidst the excitement of the day and the general revelry that comes after a team you have rooted for since you were a child makes the Super Bowl (Go 49ers!), I noticed an interesting trend in both contests: diminutive running backs. Among the players that carried the ball Sunday were Ravens RB Ray Rice (5’8”), 49ers RBs Frank Gore (5’9”) and LaMichael James (5’9”), Patriots RBs Danny Woodhead (5’8”) and Shane Vereen (5’9”) and Falcons RBs Michael Turner (5’10”) and Jacquizz Rodgers (5’6”).
None of this diminishes the point that going into the season with just McKinnon and Asiata would be less than sound. But we don't know either way about McKinnon....he hurt himself lifting weights.
But small and short are 2 different things. Jerrick Mckinnon is a big dude. I'm fine drafting another back....better yet picking up a solid FA ....but if they do it before round 4 I'll be disappoint.
