Really a no-lose deal for Bridgestone, outside of the endorsement money obviously. It's not like their reputation is going to take a huge hit if Tiger's game doesn't come back, and should he become competitive again - they get a little more advertising bang for their buck.
It's not like Bridgestone is paying these handsome endorsement deals to a lot of players. The other factor is more a rhetorical question. He might still move the interest needle, but is his game going to return to the level where he can more confidently command endorsement money comparable to that of Dustin, Rory, Jordan, Jason, etc.? Or does he automatically qualify for that type of money based on his name and overall career?
He used to never have to be concerned about endorsements that packaged overall performance-based criteria as part of the deal, but I do wonder if that has changed now.
