Some takeaways:  

• Of those 17 games, 14 involve an SEC team with Ohio St/Oregon, USC/Michigan, and Colorado/Nebraska the only games to break 5M without an SEC team involved
• In total each conference is represented
  • SEC: 22 times (11 different teams)
  • Big 10: 8 times (5 different teams)
  • ACC: 2 times (Clemson + Miami)
  • Notre Dame: 1 time
  • Big 12: 1 time (Colorado)
• The 6 biggest Big 12 games all involved Colorado. Only 5 Big 12 involved games without Colorado have done better than Colorado's 7th best performance (2.02M). No Big 12 game has broken 3M without incoming Colorado. The non-Colorado Big 12 games to break 2M are 
  • West Virginia / Penn St 2.99M
  • Kansas St / Arizona 2.58M
  • Iowa St / Iowa: 2.28M
  • Utah / Oklahoma St 2.14M
  • Utah / Baylor 2.08M
  • This means 10 of the top 11 Big 12 games have involved a new addition
• Over half of the 5M+ games (9/17) involved at least one team that changed conferences in the offseason.
• Another 3 involve some of the most desired potential additions (Notre Dame, Clemson, Miami). Florida St doesn't show up...but barely since they did get 4.99M against Georgia Tech.
• The teams that show up the most are
  • 4x: Texas, Alabama
  • 3x: Georgia, Oklahoma 
  • 2x: Tennessee, Michigan, USC
  • 1x: Ohio St, Oregon, LSU, Notre Dame, Texas A&M, Clemson, Kentucky, Miami, Florida, South Carolina, Colorado, Nebraska, Auburn, Wisconsin
