I’m of the belief that when you look at say, the top 20 players in the pro ranks, that the difference in their “skill levels”, is infinitesimal. Yet almost as a rule, there are perhaps a third of those 20 that are are always in the top spot in finishes, another third that always end up in the middle, and the last third that are near the end of that 20 regarding their competition finishes. So given the minimal difference in physical skills, it becomes clear that the difference is what they possess inside, grit, heart. Some have it in spades, some do not. It’s just one of those variables that is difficult to develop if they don’t inherently have it “in them”.
