OT: Will players eventually push an expanded playoff?

I completely agree with Mo Hurst sitting out if the Outback if he decides to do so. But it brought a question to my mind - Will it be the players decisions in bowl games that eventually push us to an expanded playoff?

People keep saying the controversy over the 4th team in the playoff will eventually lead us to 8, but there is no incentive for the bowl people to do away with their games when they make money. 

However, If more and more players end up sitting out what are truly meaningless games, the bowl games then become even more meaningless.  The only way to keep the best players from playing might eventually be to make the games meaningful.  Would a Mo Hurst, a Christian McCaffery or a Leonard Fournette skip a playoff game with their team having a chance to play its way to a championship?
