I should have mentioned that Auburn, Florida, and Texas only have a capacity of 10.8K or less... so filling those arenas doesn't present as much of a challenge for those programsas BYU's 18K capacity Marriott Center which finished #5 nationally in avg MBB attendance this year and is perrenially top 10
Also, Texas is apparently roping off 4K in their "upper bowl' seating and calling it a decreased capacity from the listed real capacity of 15K
Only four schools averaged 100% in "percent capacity" for both Football and Men's Basketball attendance this year:
Auburn
BYU
Florida
Texas
