You make great points, but one thing I have noticed is teams that were in the running for the playoff and didn't make it, usually played like dog sh!t in their bowl games.
I just don't think you can put too much stock in what a team does in a meaningless bowl game after they just missed out on a shot at a title.
Nah. We're talking about BCS/New Year Six Bowl Games. These are not meaningless games.
In 2008, Alabama played Utah in the Sugar Bowl. Bama was the #1 team for the last 4 weeks of the regular season - and they hadn't played in a BCS bowl game since 1999. Had this been the juggernaut that Saban had built up for over a decade, then I could see that game not meaning as much (the 2013 Sugar Bowl against Oklahoma might be a better example). None of these Bama players had been in a bowl game of that magnitude before.
In 2009, Boise State beat the Pac 10 Champs, Oregon in the regular season. And then they took down the #4 team, previously unbeaten TCU, in the Fiesta Bowl. That game meant A LOT to both sides.
In 2010, TCU took down the #4 team, Wisconsin, in the Rose Bowl. I've never heard anyone say the Rose Bowl was a meaningless game. The Rose Bowl, after all, is commonly referenced as the "The Granddaddy of Them All."
The 2017 game between Auburn and UCF I suppose you could make an argument. Auburn had beaten both Georgia and Alabama (the two teams in the title game), so playing in the Peach Bowl was probably a bit of a let down. However, Auburn hadn't been in a BCS/New Year's Six bowl game since the 2013 season. And since the BCS era began in 1998, Auburn had only played in a combined 4 BCS/New Year Six bowl games. It would be disgraceful if Auburn, a program that isn't annually in the top 5/10 like their rivals, didn't put in a full effort for a NY6 bowl game.
