Finally someone who has a legitimate point. Charles Barkley, a top 5 SF all time did prove to have a horrendous golf swing, not all athletes can cross over. This however was a fat Charles and I know little about when he began his acquisition of the beautiful game. We can only infer that Phil would likely have a shot at LHW.
As for evidence of contenders in their later years we can look at Romero, who is 40 and is head and tails above anyone in the division from a physical stand point, or TRT Vitor who was kicking young guys heads off as if he were that old dude with the wispy beard in Kill Bill with the crazy eye brows.
I think with the gradual nancification of modern day society, moving more towards more SJW and soy boy style fear of competition, combining with CTE study coming to the forefront.. The talent pool for MMA is only going to become increasingly shallow. I feel that the amount of contenders in some of the upper weight divisions is already petering out.
We are almost going to have to PRAY some of these athletes start making their way over from the PGA.
