its a lacking aspect on tour. Events with course like these separate the wheat from the chaff and are truly a test that rewards the best of the week.
last week's course was a joke and should never be allowed to be used in an event of that importance. Taking Nothing away from DJ, he had his A+ game and would likely have prevailed no matter the venue.
that all said, tough courses like this week and a US Open set up are probably too punishing week in and week out. Playoffs and majors need to be hard, other events can be easier.
i do really wish they would provide more punishment for wayward tee shots week in week out. Increase the rough a bit and furrow the sand traps as bunkers are almost an advantage to the rough and dont penalize the player for an errant shot
