Bowl games aren't my thing either, but I'm surprised so many are this apathetic about the sport in general. I don't buy that they're meaningless, not when the samples we use to determine the quality of teams and conferences are so small. I'm happy to root against the ACC because these bowl games matter for recruiting and national perception a lot more than you'd think. A good showing for a program like Temple against Duke, for instance, goes a long way towards cementing the narrative that they're still growing post Matt Rhule.
My impression is that most of the players bypassing the bowl games come from teams that had disappointing seasons and are just kind of ready to move on/get the draft process started, but I could be wrong.
