The only other major issue as it relates to TV Network distributions to conferences is the non-football interest:
Basketball is the #2 revenue generating sport. The ACC (5), Big Ten (10), and SEC (6) all having the most teams in the top 30 of attendance. The Big 12 has three, and the Pac-12 has one; while there are 5 teams outside the P5. As a conference, the Pac-12 barely ranks ahead of the MWC and significantly behind the other four P5 conferences and the Big East.
Hockey, in some schools, is a revenue sport; especially up north. The Big Ten claims 6 of the Top 10 spots in attendance there, with the other 4 going to the NCHC (the SEC of hockey); they also have #12 on the list (Notre Dame). Wisconsin regularly draws over 10k per game; despite not being competitive lately. With a 6,523 average attendance at home hockey games, the Big Ten hockey conference rivals the Pac Ten in BASKETBALL attendance. The Pac-12 only has one team fielding this sport, and that is a new program in Arizona State that ranks 50th (last) in the nation in attendance. DU averages over 5,000 per game.
Baseball is a revenue sport at some schools; especially down south. The SEC claims all spots in the top 5 of attendance and 11 of the Top 30 positions. The Big Ten has 4 spots in top 30, ACC (5), Big 12 (4), and the Pac-12 has 3. LSU draws over 10k per home game; and the SEC conference averages over 5,000 per game.
Wrestling is a very popular sport in certain regions of the country as well. The Big Ten absolutely dominates here. With Iowa (9,000 avg) being #1, Penn State #2 (7,700), and Ohio State #3 (6,600) and the conference holding 7 of the top 10 spots. The Big 12 has 1 entrant with Fresno State and Lehigh also being ranked. All of the top 10 are over 2,000 per contest.
Lacrosse is a revenue sport in the Northeast/Great Lakes region. Exact attendance figures across the NCAA are hard to compile, however The ACC and Big Ten certainly have the largest fanbases. With Syrace, Virginia, Duke, and Notre Dame in the top 10 the ACC leads the way; Syracuse is usually #1 or #2 with over 4,000 per game. Maryland is their main challenger for attendance with one season over 5,000 per game and 3,000 the next. Michigan and Johns Hopkins (affiliate Big Ten member) round out the top ten entrants for the Big Ten. Army, Navy, Albany, and DU regularly exceed 2,000 per game.
In women's sports, the most popular are:
Basketball: South Carolina leads the way with over 13,000 fans per game and the SEC claims 3 of the top 10 and 7 of the Top 30 spots; while the Big Ten has 8 of the top 30. The Big 12 claims 5 of the top 30, ACC has 4 of the Top 30, while the Pac-12 only has 2 of the top 30; with the highest ranked team at #16 (Oregon State). Note: Gonzaga ranks #11 and New Mexico #18.
Gymnastics: Utah leads the way here! woohoo. With over 15k fans in attendance on average they are the #1 women's sport in the country. UCLA (5,400) and Oregon State (3,500) both rank in the top 12. The SEC dominates the rest of the Top 12 with spots 2 thru 6 and 11, 12. Alabama is the only other program with over 10,000 fans per meet (13,500). Georgia and LSU are just short of that milestone with over 9,000. The Big Ten and Big 12 have 1 entrant in the top 12 each and no ACC program.
Volleyball: Only 5 teams averaged 3,000 fans or above and 4 came from the Big Ten; led by Nebraska (8,210). Hawaii was #2 at 6,759. Big Ten also ranked #6, 7, and 9. The SEC had the 8th ranked team and Big 12 #10. The top ranked Pac-12 team was Washington at #13 with just over 2,000. Note: CSU ranked #14.
Hockey: Only 1 team comes close to 3,000 fans and that is Wisconsin. Minnesota ranks #2 at just around 2,000 per game.
The point of this is that in addition to fall football, the Big Ten (Basketball, Hockey, Wrestling, Lacrosse, Volleyball, and Baseball) and SEC (Basketball, Baseball, and Gymnastics) field many other sports that have significant interest and fan following. The ACC and Big 12 rank ahead of the Pac-12 as well across the board. Their networks have content that are in demand all season long from their fanbases; even across gender lines. The Pac-12 is lacking in this full complement of popular programming.
With many of the most popular participation sports in the west being skiing/snowboarding; surfing; motocross, rodeo, eSports, and MMA not being fully-fledge NCAA sports or are not a part of the traditional "conference" model (only CU and Utah field teams from the Pac-12, but compete in RMISKA) the Pac-12 could lead the way in bringing those sports into the "conference umbrella" and on their TV network.
