I agree, but you claimed a six footer is a "gimme". Not true.
You don't average 27 putts per round unless you are hitting from 20 feet or better.
That just isn't the case. The way pros average 27 per round is by placing their approach shots close to the pin.
Or missing a lot of greens and being a good chipper.
I would agree the guys who are putting in th 27-28 area are knocking a lot of stiff irons but you still have to be able to make some putts. From 6 feet you have to be almost automatic. I can tell you that television really distorts the lenght of the put. 20 feet just isn't that far from the pin.
