My solution is a little more elaborate, but would be amazing, imo.  Here's what I'd do:

 

First you would have to realign college football.  Now, it'd be too complicated to permanently rearrange the conferences, so this format would be exclusively for NCAA football.  Imo, The NCAA should take on all responsibility for the scheduling and administering the games (i.e. referees no longer being assigned my conference), but I digress.  

 

NCAA Div 1 has 128 teams.  Divide into two leagues... let's just say A and B for now.  They use the same league format and follow the same playoff/championship format, but, for all intents and purposes, are separate leagues.  They won't interact.  

 

The first year would be controversial because you'd need to invite the 64 best teams into league A.  When you think about it, there aren't really 64 great football teams, so you're basically just slimming down the playing field.  Fear not, Kent St fans, as the other 64 teams will get the opportunity to join the A league if they play well (more on that to come).  League A and B are divided into 4 conferences roughly based on geography, let's just go with A-SEC, A-SWC, A-NWC, and A-NEC (do the same thing with B league: B-SEC... etc).  Each of those conferences will have two divisions... we'll just do east and west for now.  You end up with 8 teams in a division.  2 divisions in a conference, 4 conferences in a league, and 2 leagues in NCAA Div 1 football.

 

Now that we'e got the structure in place, let's talk about competitive scheduling.  The knock on most systems is that the season gets too long when we look at adding a playoff, so we need a system that both has a relatively short season AND maximizes competition.  I think I have the solution to that as well:

 

Each team plays the other team in their division once a year.  That is 7 games right off the bat.  Each team will also play against one corresponding division team from the other 3 conferences (e.g. A-SEC East plays A-SWC East).  That will be on a rotating basis, so over 8 years, they will play every team the other conference division has to offer.  That brings your game total to 10.  After that, every team is then ranked in their division, 1-8.  The eleventh game of the year is the conference championship game.  That weekend each team in the division squares off against their conference counterpars; the highest rated team in the A-SEC East plays the highest rated team in the A-SEC West... all the way to the bottom, where the lowest ranked team in the division squares off against the lowest team.  

 

Now every team in each league has played at least every conference, division and team in their respective leagues, and it only took 11 games.

 

Remember where I made the appeal to Kent St fans?  Here's where it pays off:  The loser of each conference game gets relegated down to League B the following year, and the winner of the conference championship game in League B gets relegated up to League A.  Man, what a treat.  I can't think of a more exciting thing in college football outside of the playoff system I am going to propose.

 

There is a 12 team playoff.  The conference champions get a bye week and home-field advantage in the quarter finals.  The 8 remaining teams are chosen by a formula that looks at wins and losses, strength of schedule, and margin of victory.  It would be something very similar to the BCS formula, only you don't need human rankings because there will be a large body of evidence to work from; there is a good measuring stick.  The formula ranks those 8 teams are ranked (only after the championship game), and they fill in a typical bracket... 1 plays 8, 2 plays 7, etc.  They will play in 4 neutral field bowl games that correspond to each conference.  For example 1 vs 8 might be assigned to A-NEC.  The winner of that game gets paired up against the A-NEC conference champ in the quarterfinals at their home field. Those bowl games can rotate each year. 

 

The semi-finals and finals are neutral site bowl games, which for all intents and purposes could be the Tostitos, Fiesta, and Orange Bowl.  The rose bowl might have something to say about that, I dunno.  Again, League B is following a similar format, so a lot of the schools that can't even compete for bowl eligibility in the current system have something to bring to the table in recruiting.

 

Welp, there's my idea.  You have a completely competitive college football league in only 15 games.  If you're still reading this, feel free to comment.
