Jimmystats: Rostering 2018

Submitted by Seth on January 22nd, 2018 at 2:00 PM

We’re off the shores of offseason and wading toward the Signing Day drop-off, and 247 recently released their final 2018 rankings, so I thought now would be a good time to update my big, useful roster database.

apologies for giving Rutgers a competitive advantage

It can tell you fun things, like how this year’s recruiting class stacks up against previous ones:


(it’s like the 2014 one, ratings-wise)

…or the NFL outcome of Michigan recruits by their relative star ratings:

As Recruit Players Rnds 1-3 Rnds 4-7 UDFA+ UDFA No NFL
☆☆☆☆☆ 17 9 (53%) 2 (12%) 1 (6%) 2 (12%) 3 (18%)
☆☆☆☆½ 64 9 (14%) 12 (19%) 3 (5%) 9 (14%) 31 (48%)
☆☆☆☆ 110 17 (15%) 16 (15%) - 1 (1%) 76 (69%)
☆☆☆½ 85 2 (2%) 7 (8%) - 1 (1%) 75 (88%)
☆☆☆ 113 4 (4%) 7 (6%) 1 (1%) - 101 (89%)
☆☆ 14 - - 1 (7%) - 13 (93%)
Walk-on 26 1 (4%) 1 (4%) - - 24 (92%)

Or how attrition is going:


(it has stayed relatively low compared to Rodriguez and Carr)


(few players are leaving without degrees)

If you download and play around a bit you can quickly find things like which players each recruiting service adored/didn’t think much of relative to each other:

Rivals Scout ESPN 247


Steve Breaston Paul Sarantos Marques Walton Benjamin St-Juste
Conelius Jones Austin White Rueben Riley Cameron McGrone
Kevin Koger Andrew Stueber Junior Hemingway Nate Johnson
Jeremy Gallon De'Veon Smith Ja'Raymond Hall Oliver Martin
Alex Mitchell Patrick Omameh Isaiah Bell Jaylen Mayfield


Ja'Raymond Hall Kingston Davis Kevin Koger Austin White
Andrew Stueber Alex Mitchell Brandon Smith Conelius Jones
Brandon Watson Keith Washington Dennis Norfleet Brad Robbins
Paul Sarantos Gabe Watson Boubacar Cissoko Myles Sims
Ronnie Bell Reuben Jones Rocko Khoury Zach Gentry


Direct Recruiting Comparisons

There’s also a second table that shows all of the recruiting data that went into my composite rankings, if you want to quickly compare where the sites put Luke Schoonmaker to Sean McKeon (they’re nearly identical):


…or place Cam McGrone among Michigan’s all-time linebacker recruits:


…or settle an argument with the guy who said Mike Hart was “just a three-star”:


(he was only barely)

…or just pull up a quick list of who’s eligible for this year’s NFL draft. I mostly use it to put the new recruits in context. Like it’s good to know Christian Turner is basically tied with Chris Evans, that Aidan Hutchinson ended up almost exactly where Ryan Van Bergen was rated, and that Jarrod Wilson and Gemon Green wound up right where Benjamin St-Juste did (German Green is down in the JT Floyd/Courtney Avery/James Rogers region). Seeing a handful of former players whose careers (and ceilings) I’m familiar with is more helpful to placing a croot than where he stands among the thousands of high schoolers of his own year whom I haven’t seen.


Starter Data

Lastly I updated the starter data with 2017 starts, which by the way featured a lot of stuff like three tight ends or three fullbacks. Those atypical start formations are more helpful than hurtful—it’s accurate to say that Gentry and McKeon were more active in the passing game, for example, than Eddie McDoom or Nate Schoenle.

You may remember last year was a crazy low bar for starts returning. Things are getting back to normal. Rather than a historically green team Michigan will have a slightly below averagely experienced team:


The big difference you can’t see here is the distribution of OL starts: last year almost all of the returning OL experience was concentrated in one guy; this year it’s spread out among six dudes: Bredeson, Ruiz, Onwenu, JBB, Ulizio, and Runyan.

The last bit highlights a flaw in reading returning starts without context: there aren’t many years in trackable Michigan history in which any of those guys would have gotten extensive playing time. It also hides regular contributors who didn’t technically start—2016 Maurice Hurst being the case example.

Digging down to game-by-game start data gives us a clearer, albeit imperfect, sample of what was on the field. And last year—to the surprise of nobody—it was historically young.


Let’s put those bars in context: the average starter for Michigan last year on both units was younger than a redshirt sophomore. Only twice in the last 20 years did any one unit dip below that mark: the 2008 offense, and the 2009 defense. I’m sure I don’t have to remind you how that went.

The bad news here is the offense at least is in for another year of historical youngness, quite likely falling below even this year. I plugged the following projection of 2018 starts: Patterson (13), Evans (6), Higdon (7), Mason (8), McKeon (11), Wheatley (2), Gentry (7), Eubanks (1), Black (10), DPJ (8), Crawford (1), and an OL of Newsome-Bredeson-Ruiz-Onwenu-Hudson, and it came out at an average year in program of 2.67, barely above 2008.

Does it matter? With the exception of 1997, the peak years do seem to correlate to the teams playing the guys who’ve been around awhile: 1999, 2002, 2003, 2006, 2011, 2012, and 2016. On the other hand Ohio State managed to put up a strong offense in 2016 despite a similarly young roster, though it should be noted they were operating under an experience QB and the young players were holes that got exploited by better teams.

(I never know what to do here with transfers who’ve started at previous stops. Considering the performance of said transfers when they have played, the most accurate thing to do is to just throw that data out—after all they’re new to the system.)

The other interesting thing I can do with starter data is to check personnel shifts. In the past I used it to show the relative mass on the field between coaches. But the Harbaughification of the offense is clear in other ways, like starting more tight ends:

AVG Skill Position Personnel at First Snap
Season(s) RBs FBs TEs WRs
Carr 0.99 0.62 1.27 2.11
Rodriguez 1.22 0.14 0.78 2.86
Hoke 0.98 0.45 1.12 2.45
2015 1.02 0.94 1.09 1.95
2016 1.00 0.69 1.77 1.54
2017 0.92 0.77 1.92 1.38


Anyway if you want to download your own copy of my data and play with it, you’re welcome to it. Just share your findings in the diaries.

please list the dates where you will be holding seminars and breakout sessions on all of this data.  Will the sessions last 1 week or 2 weeks ?  Holy shit ... that is a lot of Jimmystats!

Go Blue !

For your data Seth, 
Spanellis is likely the C.

Ruiz is a G.

Bredeson is kicking out to RT. 

Hudson or Newsome likely the other T.


so..     Hudson  Onwenu  Spanellis  Ruiz  Bredeson          

Maybe Newsome returns...

My first observation, which is probably obvious to anyone who has been paying attention to the team and recruiting over the years, is that the very top-starred recruits who have ended up not contributing are clustered in the RB position. 

Thoughts to why this might be?  Poor rankings?  Poor coaching?  Poor OL-play?  Just bad luck?  Our run offense for a long while prior to this year (not including Denard) has not exactly been very good, and even a good RB can't do much if there is nowhere to run, unless they are Barry Sanders. 


January 22nd, 2018 at 7:15 PM ^

just a note of caution: Peters, with three years (?) of eligibility left, even if slow to absorb the scheme, still possesses considerable upside. Patterson will have to be a quick study to slot into another historically youthful offensive side and excel.

Always look forward to seeing the experience and age of our players. I knew we were young and inexperienced last year, but got damn. A little thrown off since I guess Hurst isn't in there as a starter but still. It makes the 2008 team look experienced.
