The margin between tour pro and high level club pro is both big and small at the same time. Ability-wise, it's not a big gap. They can all bomb it 300+ of the tee and hit irons with ungodly amount of spin. Arrogance-wise, the tour pros believe that they can make every shot from everywhere. The average club pro doesn't have that same belief. BLOCK probably could have carved out a nice career as a journeyman pro bouncing between the PGA Tour and whatever the AAA Tour is called this year. He makes a more consistent income as a club pro is Southern California and cleaning up on the club pro circuit there.
