In its maiden year, the FedEx Cup Playoffs served up a quartet of courses that players just feasted on.
Steve Stricker and Phil Mickelson opened up the low-scoring bonanza with 16-under-par performances in their respective victories at the Barclays and the Deutsche Bank Championship, and the red figures would soon climb higher and higher.
At the BMW Championship, Tiger Woods stormed to victory with a 22-under total and topped the feat the very next week at the playoff finale (the Tour Championship) with his red number reaching 23.
Overall, the winners of the four events that comprised the 2007 FedEx Cup went a whopping 77 strokes below par in their victories.
It seemed that every playoff event would become a shootout every single year, making these venerable courses appear no more difficult than your average pitch-n-putt.
But, that 2007 birdie barrage turned out to be an anomaly.
In the four years since that red-splattered opening salvo, the courses have become more stingy, only allowing cumulative totals of somewhere between 51 and 55-under par each year.
While that may still be far from the test that say a U.S. Open presents, these higher scores show that these courses aren't pushovers.
And with the addition of a U.S. Open site in Bethpage Black (instead of the ripped apart Plainfield layout) for the Barclays, matters may get even tougher (don't expect Bethpage to play quite like an Open though).
