This discussion ended when Koepka won at a softer than expected Erin Hills,
followed by another Koepka win at a widened, then narrowed--- firmer/faster/deader-slower- firmer/faster/deader , slower/ softer Shinnecock (the best manipulation the USGA could come up with on short notice-to be fair, they had an outbreak of perfect weather)
The icing on the cake was winning at Bellrieve after a lot of rain, then at a super tough Bethpgage in windy conditions.
This guy is good
