I read a lot of chatter online about how the league is devaluing the RB position, but IMO that's misleading. The RB position has been devalued for the past decade and it has almost always required a special talent to justify such a high pick at this position.
I'd argue that the lack of a first round RB in 2013 and 2014 (I'm guessing) has a lot more to do with the players themselves rather than league-wide trends. Simply put, there hasn't been a good enough RB prospect in either of these two drafts to justify that high of a selection.
I just threw together a spreadsheet with workout information for all 27 RBs drafted in the first round from 2004-2012.
Here are the averages in a few key physical categories:
Weight - 216.7
BMI (body thickness) - 30.3
40 - 4.44
Vertical - 35.8"
Broad Jump - 10'3"
That's a pretty good description of the generic first round caliber RB from a workout numbers standpoint.
If you sort by weight, you find that 21 of 27 RBs were at least 210 pounds. Of the 6 "small" backs who weighed below 210 pounds, here are the averages:
40 - 4.34
Vertical - 36.3"
Broad Jump - 10'5.5"
If you sort by BMI, you find that 21 of 27 RBs were at least 29.6 or higher. Of the 6 "small" backs who were below that threshold, here are the averages:
40 - 4.33
Vertical - 35.9
Broad Jump - 10'5.3"
Here are the numbers for the 21 RBs whose weight puts them in the "not small" group:
40 - 4.47
Vertical - 35.6"
Broad Jump - 10'2"
Here are the numbers for the 21 RBs whose BMI puts them in the "not small" group:
40 - 4.47
Vertical - 35.75"
Broad Jump - 10'2"
The most significant difference between the two "small" groups and the two "not small" groups is the 40 time. The jumps are marginally better for the small backs, but the difference is minimal. However, the 40 times are over a full tenth faster on average. What this means is that "small" backs (either according to weight or body thickness) need to run REALLY fast to get picked in the 1st round.
For a "not small" RB (one with a 29+ BMI and/or a weight of 210+ pounds) to get picked in the first round, he probably needs to be within shouting distance of a 4.47 40, a 35.5" vertical, and a 10'2" broad jump. Anything that's more than .05 slower in the 40, 2" shorter in the vertical, and ~3-4" shorter in the broad jump starts to look like a dealbreaker unless he's absolutely exceptional in one of the other drills (i.e. Mendy and Ronnie bombing in the jumps, but running insanely fast for their size). If you're a "small" RB (sub 29 BMI and/or sub 210 pound), you want to be in the same ballpark in the jumps and you probably also need to clock at least a 4.3X to expect a first round draft slot.
Apply these restrictions to the 2014 and 2013 draft classes. You'll see pretty quickly why there isn't a first round talent in either. Bell, Lacy, and Ball were nowhere near hitting these marks. Gio Bernard was too light without elite speed. Knile Davis and Christine Michael basically fit the physical profile, but they had glaring production/injury issues. This year, Hyde and Hill are nowhere near hitting the right marks. The guys who tested well (Sankey, Seastrunk, and Mason) are all below 210 pounds without the requisite speed for that size.
Charles Sims, Terrance West, Jerick McKinnon, and Andre Williams kind of fit the mold from a measurables standpoint, but then nobody has ever argued that those players are first round talents. The workout numbers are very much a "necessary, but not sufficient thing." In other words, "you must be this athletic to be a first round back, but being this athletic doesn't guarantee that you'll be a first round back."
Add it all up and it doesn't look like there's a first round back in this draft. That's not because the league is moving away from drafting RBs in the first round (which will probably be the prevailing narrative that we hear for the next 12 months after the draft), but rather because for whatever reason there simply haven't been any RB prospects in the last two years who possessed the right combination of production, high subjective ratings by scouts, and excellent tangible measured athleticism.
