So signing day is over. And Missouri’s class of 2018 is all but assembled.

As you look up and down the Tigers’ newest crop of signees (Rivals.com ranks it 41st in the nation as of this typing, which is right about at the average of the four classes that came before it), I want you to consider this bit of research I started at the Columbia Daily Tribune and continued here at Rock M Nation. It began with the class of 2002, Gary Pinkel’s first full class as head coach and the first year of the ever-helpful Rivals.com database.

When you’re trying to determine just how important every single signee is to the future of Missouri football, it’s good to give you a frame of reference as to how likely it is that your average Missouri signee achieves different levels of achievement during their Tigers careers.

A little more than half of them will ever start a game. A little less than a third of them will hold down a starting job for more than a year. A full 20 percent of them will never see the field.

Here’s some helpful information on criteria before we get started:

• Only classes that have had at least five years to complete themselves are factored in the likelihood percentages. The 2013 class is the most recent one included, as all of its redshirt seniors have moved on. I included more recent classes (2014-17) in the study so you can take a look at how they’re shaping up, but they don’t factor into the probability percentages.
• A "starter" is defined as someone who started at least half of the team's games in a given season. This year, for example, Yasir Durant was a “starter.” A.J. Logan and Markell Utsey, technically, were not, because they started only six of 13 games. This leads to odd quirks like Chase Coffman being a three-time all-conference performer, yet only a one-year starter.
• A "spot starter" is anyone who has ever started a game, but never started at least half of them in a season. Yes, I realize someone who started one game in his career isn't exactly a "spot starter," but he started in a spot. So let’s get literal with it.
• "Played" means just that. If you played at least one regular-season game in a Missouri uniform, you fall into that category.
• Specialists were not counted as starters, even if they handled the team's primary kicking or punting duties. They are not technically starters, per the participation report.
• All-conference selections were determined as first- or second-team choices by either the coaches or the Associated Press. Players who made both coaches and media lists in a year were only counted as one. All-America selections were determined based on the five teams officially recognized by the NCAA.
• Players who began their careers as walk-ons were not included in the study, as they were not technically part of signing classes. Sorry, Jonah Dubinski, Adam Ploudre, Max Copeland, Randy Ponder and Colin Brown.
• Players who signed out of high school, didn't qualify, then were signed again out of junior college were counted in the second signing. They were still used in the class count from the first signing year as well, as it was ostensibly still a signing spot taken up by a player who did not become a part of that class.
• Players who transferred in are not counted, as they were not part of the signing classes for ranking purposes on Rivals.
• "Class record" is determined by the team's record in the five seasons after the signing class came in.

So, knowing all that...

Of the 271 players Missouri signed from 2002 to 2013, here is the percent likelihood that a player would...

• Play in at least one game: 79.7 (216)
• Start at least one game: 52.4 (142)
• Be a starter for at least a year: 45.8 (124)
• Be a multi-year starter: 30.3 (82)
• Be a three-year starter: 14.0 (38)
• Be a four-year starter: 1.85 (5)
• Be an All-Conference player: 18.1 (49)
• Be a two-time All-Conference player: 5.54 (15)
• Be a three-time All-Conference player: 0.74 (2)
• Be an All-American: 2.58 (7)
• Be a two-time All-American: 0.37 (1)

To be updated in the spring...

• Get drafted: 11.1 (30)
• Get drafted in the first round: 2.95 (8)

---

Now, how do we quantify how successful a class is as a whole? It’s tricky. There are many things to consider.

The proportion of signees who played? Who started? Who held down a starting spot for at least a year? For multiple years? Who were all-conference or All-America performers? Who got drafted? What about the on-field success of that class?

We tried to throw it all into a blender and come up with something for you.

We assigned points to each player for playing, starting, one point each for how many years he was a starter, points for all-conference selections (two for first-team, one for second-team), points for All-America selections (three...because it’s a step up from all-conference?), then points for which round of the draft they went in (3.5 for first round down to 0.5 for seventh round).

Then we divided each category by the size of the signing class and added them all together — plus the class win percentage — for a total.

Not perfect, but good enough to start some arguments, right? Here’s what we got:

Now, you’ll see that 2014-17 aren’t done. And 2013 isn’t quite done yet, as J’Mon Moore will, in all likelihood, add to that draft total.

But, taking a look around, which are the strongest classes?

2008

Five all-conference players, as well as three (Jacquies Smith, Aldon Smith and Michael Egnew) that were multi-year. Not to mention Egnew’s All-America selection and first-round draft picks in Aldon Smith and Blaine Gabbert. On a macro level, you had 21 of 23 play, 19 start at least a game and 16 be a starter for at least a year. And they had a .631 percentage over five years.

2010

More of a workmanlike class, with seven all-conference selections, and E.J. Gaines and Marcus Murphy pulling double duty. Plus five draft picks (Gaines, Murphy, Kony Ealy, Bud Sasser and Mitch Morse), though no first-rounders, and six guys who were three-year starters. Plus a .697 win percentage.

2011

A sneaky good class, especially considering how it ranked 48th in the nation coming out of high school. They got a lot of mileage out of four draftees and two first-rounders (Shane Ray and Sheldon Richardson) out of a 17-member class. Plus Ray’s All-America nod and Kentrell Brothers making two all-conference teams.

As far as the individual characteristics:

• % Played: 2008, 2011, 2010
• % Started: 2008, 2011, 2010
• Starters: 2008, 2010, 2003
• All-Conference/America: 2006, 2005, 2010
• Draft: 2011, 2008, 2012
• Winning: 2006, 2007, 2010

Now let’s take our class rankings 1 through 12 and see how the classes ranked coming out of high school:

25, 21, 48, 39, 47, 28, 31, 29, 40, 33, 41 (with possible upward mobility), 46

Fluctuation, sure, but interesting that the two most highly regarded classes entering Missouri (2008 and 2010) were definitely among the best classes when all was said and done.

(A little sidenote: Jeremy Maclin and Sean Weatherspoon were probably about the most valuable players on here. They combined for 33 points total — Maclin 17.5, Weatherspoon 15.5 — or about 37 percent of the 2006 class total)

---

So how do the as-of-yet-unfinished classes look like they’re stacking up?

• The 2014 class has only five more opportunities to pile on multiyear starters (Paul Adams and Kevin Pendleton possible three-year guys; Nate Brown, Brandon Lee and Samson Bailey possible two-year). It also has yet to claim an all-conference award and will need to go at least 9-4 this year to beat out 2002 for the worst class win percentage.
• 2015 has a possible four-year starter (Drew Lock) and two all-conference players (Lock and Marcell Frazier) to its credit. It also has the possibility of moving six more players (Lock, Emanuel Hall, Johnathon Johnson, Terry Beckner Terez Hall and Cam Hilton) up through the multiyear starter ranks. Pretty solid class, but it’ll have to go 19-7 over the next two years to be better than 2002’s win percentage.
• 2016 already has an all-conference player (my man Albert) and can move five (Okwuegbunam, DeMarkus Acy, Trystan Castillo, Cale Garrett and Tre’Vour Simms) into the realm of the multiyear starters this year.
• 2017 already has two starters (Yasir Durant, Adam Sparks) and two who have started (Rashad Brandon and Jordan Ulmer) after one year, as well as 56 percent who have played at least a game. Not a bad start.
