Honestly, if Ben Shelton wasn't still playing, I would have stopped paying attention to this tournament by now. He's the only one of the remaining players left that really moves the needle. All the others are over 25, and you pretty much know what their ceiling is (spoiler alert: all of them are good, but never really going to be elite). Shelton, on the other hand, still has the potential to be an elite player (at least he's still young enough to make you think that he still might have that next gear in him).
If Shelton wins the tournament, it could be marketed as the first (of possibly several) big titles for a potential elite player. If anyone else wins it, it feels like just another title won by a good, but not elite, player (when the top players were out).
