To me this is the biggest indictment of Lebby because it's so simple. You should always defer. Always. The math is clearly in favor of deferring. It's the only time in the game you can get two offensive possessions in a row.
1) It’s not really the only time you can get 2 offensive possessions in a row. Turnovers happen all the time. Onside kicks. Muffed punts, etc
2) The offensive possessions aren’t really “in a row” when you have a half hour of rest time between them. That greatly dilutes much of the advantage with a tired defense. And the 1st half has to play out a very specific way for it to happen in any sort of advantageous way.
My understanding is that analytics data is slightly in favor of deferring in the NFL, where the talent is evenly distributed, all the stadiums except for 3 or 4 are sterile / mostly inclement weather-proof, have predictable wind patterns, and few localized raucous fan sections.
College football is just different, there’s not nearly enough data to say what’s better or worse for coin toss choices. There’s way too many variables to draw meaningful conclusions. Sometimes, you’re going to want to pick which side of the field you’ll be on in the 4th quarter. A game that starts under sunshine but heavy rain forecasted starting in the 2nd quarter, you definintely want the ball first.
It simply isn’t some binary, universal right/wrong choice at the college level. I’m no Lebby apologist at all, but this is a non-issue. Lot’s of college coaches take the ball first more often than not.
