Myles Gaskin, J.K. Dobbins among most well-rounded college running backs in 2018

Meanwhile, Mississippi State has two of the most exciting mobile quarterbacks in the country.

Let’s keep right on rolling with our as-late-as-humanly-possible look at last year’s player stats and what they might mean for 2018 and whatnot.

Last week, we took a look at receiver data. Now we move on to the ground game.

Once again, this is another post intended to explore the marginal efficiency and explosiveness data I discussed way back in January.

* Marginal Efficiency: the difference between a player’s success rate* (passing, rushing, or receiving) or success rate allowed (for an individual defender) and the expected success rate of each play based on down, distance, and yard line.

* Marginal Explosiveness: the difference between a player’s IsoPPP** (passing, rushing, or receiving) or IsoPPP allowed (for an individual defender) and the expected IsoPPP value of each play based on down, distance, and yard line.

For offensive players, the larger the positive value, the better. For defensive players, it’s the opposite — the more negative, the better.

* Success rate: a common Football Outsiders tool used to measure efficiency by determining whether every play of a given game was successful or not. The terms of success in college football: 50 percent of necessary yardage on first down, 70 percent on second down, and 100 percent on third and fourth down.

** IsoPPP: the average equivalent point value of successful plays only.

For each play, there is a bar established for expected efficiency and explosiveness based on down, distance, and yard line. From there, we can compare team or individual success to an interesting baseline.

Once again, the idea is to explore efficiency and explosiveness, using my two primary tools (success rate and IsoPPP) and applying adjustments based on expectation. You can’t rip off a 70-yard run from your opponent’s 20, so setting a moving bar can help us get closer to the truth. So, too, can evaluating successes and non-successes based on whether it was third-and-1 or third-and-19.

You can download all of 2017’s rushing data here. That’s a link to a Google doc with all rushes and players broken out into categories — running back, fullback, quarterback, WR/TE, and other.

Let’s again start with the high-volume guys.

What can fancy math teach us about the guys who carried the ball the most last year? Here are the 83 RBs who got at least 150 carries.

First things first: it must be noted that, of these 83 players, only 28 produced a marginal efficiency above zero percent. As with what people have begun to firmly establish on the pro side — I highly recommend picking up a copy of the Football Outsiders Almanac 2018 and checking out the “establishing the run” essay by Ben Baldwin — running is a reasonably lower-ceilinged endeavor. It’s lower-risk, too, and some teams have certainly figured out how to run more than others, but for a majority of feature backs, handing them the ball was likely to put you behind schedule.

It was also far less likely to produce big plays — only 18 of these 83 produced a marginal explosiveness above plus-0.0 points per successful run.

That said, a few stood out. Here are the 22 players who rated in the 50th percentile (among the players in this sample) in both marginal efficiency and explosiveness. Players in bold are returning in 2018, and players with an asterisk were in the 80th percentile in both.

• AJ Dillon, Boston College (1,589 yards, -1.2% mEff, -0.6 mExpl)
• Alexander Mattison, Boise State (1,086 yards, -1.6% mEff, -0.13 mExpl)
• Dalyn Dawkins, Colorado State (1,399 yards, +2.8% mEff, -0.12 mExpl)
• Darius Tice, USF (943 yards, +3.1% mEff, -0.07 mExpl)
• Devin Singletary, FAU (1,920 yards, +5.7% mEff, +0.00 mExpl)
• Ito Smith, Southern Miss (1,413 yards, +2.3% mEff, -0.10 mExpl)
• J.K. Dobbins, Ohio State (1,403 yards, +6.0% mEff, +0.01 mExpl)
• Jarvion Franklin, WMU (1,228 yards, -1.0% mEff, -0.06 mExpl)
• Jeffery Wilson, North Texas* (1,215 yards, +3.8% mEff, +0.05 mExpl)
• Jonathan Taylor, Wisconsin (1,977 yards, +2.9% mEff, -0.11 mExpl)
• Jordan Wilkins, Ole Miss (1,011 yards, +2.5% mEff, -0.07 mExpl)
• Josh Adams, Notre Dame (1,430 yards, -0.6% mEff, +0.19 mExpl)
• Lexington Thomas, UNLV (1,336 yards, -0.6 mEff, +0.21 mExpl)
• Myles Gaskin, Washington* (1,380 yards, +3.6% mEff, +0.05 mExpl)
• Nick Chubb, Georgia (1,345 yards, +2.9% mEff, -0.11 mExpl)
• Patrick Laird, California (1,127 yards, +2.7% mEff, -0.13 mExpl)
• Rashaad Penny, SDSU* (2,248 yards, +2.8% mEff, +0.31 mExpl)
• Ronald Jones II, USC (1,550 yards, +3.0% mEff, -0.09 mExpl)
• Royce Freeman, Oregon (1,475 yards, +6.2% mEff, -0.12 mExpl)
• Saquon Barkley, Penn State (1,271 yards, +1.1% mEff, +0.08 mExpl)
• Sony Michel, Georgia* (1,227 yards, +6.5% mEff, +0.15 mExpl)
• Xavier Jones, SMU (1,075 yards, +0.0% mEff, +0.01 mExpl)

Rodney Anderson of Oklahoma, by the way, nearly made the list, too. He had the best marginal efficiency by far and was in the 44th percentile for explosiveness. Similarly, Stanford’s Bryce Love had by far the best explosiveness (plus-0.63 mExpl, more than double Penny’s plus-0.31) and was in the 40th percentile for efficiency.

The most all-or-nothing feature runner of 2017: UMass’ Marquis Young — fifth percentile for mEff (minus-9.5 percent), 98th percentile for mExpl (plus-0.26).

What about the best rushers from the QB position?

Breaking: option quarterbacks run a lot. Lamar Jackson was the only QB with 200+ rushes who didn’t qualify as a triple-option guy.

Here are the best of the best, the 19 rushing QBs who ended up in at least the 50th percentile in both efficiency and explosiveness:

• Lamar Jackson, Louisville (1,759 yards, +14.3% mEff, +0.20 mExpl)*
• Nathan Rourke, Ohio (1,008 yards, +21.4% mEff, +0.08 mExpl)*
• Nick Fitzgerald, Mississippi State (1,025 yards, +9.7% mEff, +0.02 mExpl)
• Stephen Johnson, Kentucky (537 yards, +12.8% mEff, -0.05 mExpl)
• Taylor Lamb, Appalachian State (652 yards, +17.3% mEff, +0.05 mExpl)

First of all, it’s unfair that Mayfield was a good rusher and a great passer.

Second, though Mayfield and Jackson are gone, there are a lot of fun, impressive rushing quarterbacks coming back this year. And two of them attend Mississippi State.
