It seems like the PGA tour could require that a full-time tour player play every event every so many years. Or, at least stratify the tournaments into levels, (A,B, and C) and set a quota of tournaments the player has to play at each level over a 3 year period - something like that. I don't see how it wouldn't be in the Tour's best interest in getting premier players at every event every year. What would be the downside of a plan like that?
