To play devil’s advocate, or to take a very jaded point of view, if the premise is that a draftable player does not want to risk injury and thus risk future earnings in the NFL, in other words, a purely financial reason, why play in a CFP either? Again, just playing devil’s advocate, but looking at it purely in financial terms (which, as far as I can tell, that is exactly how NFL draftable players in non-CFP bowls look at it), an NFL-caliber player is risking future earnings as much in a CFP game as in a non-CFP game. And if your CFP team advances, that increases the risk of injury. I know it’s for the championship, but only two teams will be vying for that in the end. So, the good players in the other CFP teams will have taken the risk for basically no reason, or rather, no better reason than those who opted out of the non-CFP bowl games.
