I don't think so. I know this is a bit off topic but, I think they would win more if they had to earn a living just by playing and not all of the other money they get. I think many of them are satisfied with just playing because of what they earn without winning. Love to see them play if they were hungry to maintain the life style they have, but without all of the "other" money in the bank. Case in point = Phil making $37 million a year without winning anything. Take that $37 million (2018) in endorsements away.
Take this away and see what they do;
Rory $34 million in endorsements in 2018
Jordan $30 million in endorsements in 2018
Tiger $42 million in endorsements in 2018
Tiger earned $1.3 million in 2018. Huge difference if he didn't have that other $42 million up front.
