So why don’t you hold out the entire starting lineup who could risk injury and 6 figure incomes?
You don't seem to realize how few college players have an opportunity to go pro. Most of those who start will never see an NFL practice squad.
But to your question, I don't choose to hold out anyone because I wouldn't deign to decide that for someone else, but I do respect the decision of anyone to not risk an opportunity at life changing income to participate in a bowl game.
I think of Jake Butt, playing for the Wolverines against my alma mater last season. He decide to play his senior year when he was predicted a second round draft pick. He had a great season and was a solid pick. Suffered a torn ACL and nerve damage that immobilized his leg initially in an Orange Bowl that meant nothing. He got a 5th round pick out of Denver, but is still on IR. He may never play again. At a minimum the injury has already cost him millions. For what exactly?
