Here, we use recruiting rankings to rank college football teams for 2015. Sure, recruiting rankings don’t always accurately access the talent of teenagers. Five star recruits fail while a three star recruit like Johnny Manziel wins the Heisman in his freshman year.
However, recruiting rankings look pretty good in the big picture. Matt Hinton showed that five star recruits have the highest chance to become an All-American, with diminishing chances for four and then three star recruits.
I developed a regression model that uses four years of team recruiting rankings from Rivals to predict on field performance. This on field performance is defined by the team rankings at The Power Rank. The regression model simply assigns a weight to each of the past four years.
Will these rankings accurately predict next season?
We’ll count down the top 26 teams of 2015 below. But don’t go telling people “ED FENG THINKS USC IS BY FAR THE BEST TEAM IN THE PAC-12.” Not true.
The regression model is a poor predictor of team performance by The Power Rank. It’s much better to just look at the year end rating from the previous season. (For you math types, the recruiting model explains 25% of the variance in team ratings, while the year end rating from the previous season explains 57%.)
This model will never describe teams like Wisconsin, a program that never has a top 25 recruiting class but contends for a conference title every year. It will also overrate programs (cough, cough, Notre Dame) that never live up to their talent level.
But hell, it’s fun to look at which teams have the most talent according to recruiting rankings. It will help pass the long 7 month off season.
Wisconsin ranks 44th. Former coach Gary Andersen, who left for Oregon State this winter, lamented the tough academic standards that prevented him from recruiting some players to Wisconsin.
TCU and Baylor rank 37th and 40th respectively. Guess coaching matters, as these should be top 10 teams next preseason.
Missouri checks in at 32nd. Low recruiting rankings haven’t stopped Gary Pinkel’s team from winning the SEC East the past two seasons.
26. Michigan State
Mark D’Antonio has produced a mighty fine team the last two seasons despite mediocre recruiting. With the probably return of QB Connor Cook, the Spartans should still be a very good team in 2015.
25. Penn State
Coach James Franklin came to State College with a reputation for recruiting, and he seems to be delivering. But can he fix QB Christian Hackenberg, the supposed NFL prospect whose completion percentage slipped from 59% to 56% from his freshman to sophomore year?
24. Arizona State
Coach Todd Graham has elevated the level of recruiting in Tempe. Arizona State was outside the top 25 from 2009 through 2013 but has drawn the 20th best class the last two seasons.
23. Mississippi State
The Bulldogs had an amazing 10-3 year (well, they could have done better with a bowl win over Georgia Tech) and translated their success into the 16th best class this season. That’s their best rank since 2003.
22. Virginia Tech
Frank Beamer is still getting good recruits to come to Blacksburg? Virginia Tech was a perennial top 25 team in The Power Rank but have fallen off since the 2011 season.
Michigan has had two successive small recruiting classes, which has reduced their team rank the past two seasons. When recalculating these rankings using average stars per recruit, Michigan ranks 17th.
20. Miami (FL)
The Hurricanes had a rough season. They ranked 17th in my ensemble rankings but finished with a losing 6-7 record. Al Golden recruited the 26th best class but 16th by average stars.
Oregon always plays above their rank by recruiting numbers. However, 2015 will be a tough test for Mark Helfrich, as he loses QB Marcus Mariota and has many leaks to plug on the defense.
Two years ago, Hugh Freeze made a big splash on recruiting day by signing multiple five star recruits on his way to the 7th best class. However, he hasn’t been able to replicate that success the last two years. It remains to be seen whether their successful 2014 season was a fluke or not.
17. South Carolina
Steve Spurrier really had issues on defense this season, as South Carolina finished 37th in my team rankings in 2014. They didn’t finish outside the top 20 the previous four seasons.
At least once during every Stanford game, I scream at coach David Shaw for some unthinkably bad decision. However, he wins games, and the 2014 Stanford team was much better than their 8-5 record suggests.
In 2014, the Sooners won a huge bowl game over Alabama and entered the next season overrated. In 2015, they blew their bowl game against Clemson and will probably be underrated heading into next season. Bob Stoops continues to recruit at the same level, so expect them to challenge TCU and Baylor for the Big 12.
The Bruins had a tremendous signing day, finishing with the 4th best class by average stars per recruit. Let’s see if this makes them into the top 10 team that people expect each preseason.
Charlie Strong recruited the 12th best class to Texas. This is a fine haul anywhere except Texas, a program that had one class outside the top 5 from 2006 through 2012 under Mack Brown.
It seemed like new coach Jim McElwain had a good National Signing Day when five star CeCe Jefferson committed. However, Jefferson still hasn’t sent his letter of intent, and Florida has the 23rd best class, their worst rank in any year since 2002.
Butch Jones recruited his second straight 5th ranked class. Perhaps Tennessee can finally overcome the curse of Phil Fulmer, the Hall of Fame, national championship winning coach they fired in 2008.
Mark Richt always recruits well. That’s why he can find a freshman (Nick Chubb) to replace the best running back in the country (Todd Gurley) when he gets hurt.
Dabo Swinney recruited the best class of his tenure as Clemson head coach (4th by team, 7th by average stars). With a healthy DeShaun Watson at QB for the next two seasons, the future looks bright for the Tigers.
8. Texas A&M
The numbers back up Kevin Sumlin’s reputation as a top recruiter. Texas A&M had its third straight top 10 class in 2015, a feat they didn’t achieve the previous 7 years. Now, they need to fix that defense that has stunk for two straight seasons.
7. Notre Dame
The Fighting Irish recruit well no matter the coach. However, their play hasn’t lived up to their top 10 recruiting rankings, even under Brian Kelly. Since he arrived in 2010, they have finished 32nd, 21st, 11th (reached title game against Alabama), 23rd and 39th in my team rankings.
It should scare the rest of the college football world that Auburn landed Will Muschamp as defensive coordinator. He was an excellent DC at Texas, and his reputation helped Auburn land top recruit Byron Cowart.
Les Miles had only the 13th ranked class by average stars. This is only the second time since 2007 that his recruiting class by average stars finished outside the top 10.
4. Florida State
The Seminoles had the top ranked class in 2015 by average stars. Jimbo Fisher needs some of these guys to step in on a defense that struggled this season.
Did these recruits see USC get gashed by Boston College this season? And they still decided to play for Steve Sarkisian and his 9-4 record this past season? USC had the top ranked recruiting class in 2015.
2. Ohio State
For a team that won the first college football playoff, a 9th ranked recruiting class (10th by average stars) seems like a poor haul. However, Ohio State didn’t have one five star recruit on their offensive line that powered their running game this season.
Duh? What did you expect? Nick Saban must be torturing himself because USC had a better ranked class (the first time since 2010 that Saban didn’t have the top ranked class by Rivals). However, Alabama still ends up at the top of these rankings that look at a four year window.
