I'm digging the evolution of this topic...
Why do golfers (in general) place so much importance on how they hit it pre-round? The lies are perfect and flat, the targets are not demanding, no fear of hazards, etc, etc. Then we go to the first tee... tree lined, OB right, bunkers left with a dogleg.
The feelings in the hands aren't the same as on the range, the adrenaline isn't the same, the consequences aren't the same, virtually nothing is going to be the same on the course as it is on the range. Yet the ever popular topic in golf is "how do I bring my range swing to the 1st tee".
When did a warm up, getting the body loose and warm, become a foreboding crystal ball for the next 4 hours? I'm certainly guilty of letting that happen in the past, but I don't recall being that way in other sports. You would show up, get used to the field/court, get loose, and get ready to compete. You can see some really dejected faces on the range before tournaments. Is it because guys use a pre-round warm up as a mini practice session? Is it because the guy next to you is striping it? Is it because you heard a pro say after shooting 62 that he had a great warm up?
