Again, I'm not saying people are going to go the extreme route like Bryson does, only that people will stop seeing size as a detriment to the golf swing and hit the weights more.
It would simply be the evolution of the sport. Big and strong tends to be the norm to succeed in most other sports. Even if I had world class talent, I'd struggle in the NHL at 5'9, 150. The days where a PGA Tour golfer could be a multiple major winner averaging 265 off the tee are gone. One day a guy averaging 285 will be considered a short hitter.
Actually a smash factor of 1.43 is pretty stellar; the "theoretical max is not quite 1.5". You can read about the physics of smash factor, if so inclined, here:
Smash Factor - Myths and Facts
If you watch golf on TV or read the golfing magazines, you have heard a lot about "smash factor". If you learn about it from those venues, you get some facts and a lot of half-truths. Let's clear up the confusion about smash factor.
Right. But my point is not everyone can do this. It’s not just a choice. In an exaggerated extrapolation...many players would simply struggle to make it on tour if in fact big and strong became the norm to succeed.
To put it in alternative terms, I see ball speeds in excess of 190 mph becoming more common on the PGA Tour in the future. It's going to be easier for more people to achieve that by being a bigger, stronger athlete than being a freak of nature.
