The bowl games, especially ones earned by 8-win SEC teams, were never considered "meaningless" until guys like Cam started declaring them to be meaningless 5 or 6 years ago. We can argue until the cows come home about who owes who what or who is a hypocrite and who is selfish and who's not, but the simple fact is this line of decision-making diminishes college football and will continue to diminish it further as the rationale is extended to late regular season games for countless teams with no shot of making the playoff.
"Meaningless" is a subjective term. On its face, every college football game is meaningless. China isn't waiting for the results of a college football game to decide Taiwan's fate and Putin's war in Ukraine isn't going to turn on a football game. In the big scheme of things, there isn't much difference between a bowl game against Notre Dame or Iowa and a regular season game against Clemson or Florida and it's only a matter of time before players start to make that same determination.
