We see that at every golf course on Tour.
The greens are tough, but they're not insane.
You win the "Completely Misses the Point" award for the day.
Hush! You're making too much sense!
No it wasn't. You took an anomaly (someone five-putting) and extrapolated that single anomaly to extremes.
I just saw a guy make a 30 foot putt. Bubba made a putt on 14 yesterday that broke 15 feet or so. The odds of making those putts are about 2%. So, it makes just as much sense (i.e. none) for me to say "the greens are so easy!" based on those anomalies as it does for you to extrapolate the five-putt.
When Brandt four-putted from 15 feet in Chicago, that too was an anomaly. The average PGA Tour pro would average 1.8 putts from that exact spot to that exact hole location. Brandt was a good putter who had a single bad hole.
You can't make sweeping generalizations based on a single occurrence of anything.
2013 PGA Tour Median player: 1.782 PPG
2014 Masters: To get to 1.782 PPG you have to go down to 15th from the bottom, well past the median value, and well into the 46 or so players that MCed.
Point remains: anomalies are horrible things by which to judge things. It'd be like taking a hole in one on the 8th hole at Oakmont and calling it an easy hole… despite it being a 300-yard par three. "It's easier to ace an easy par three than a tougher one." One-time events are anomalies. You must look at the overall average. Brand Snedeker, on average, is not much better or worse at Augusta National.
The importance of putting is over-stated. Bubba has created a lead by hitting greens, and has lost the outright lead because he's missed some greens lately.
