Ah, we can all learn from him and a lot of other people!
Some people have an inate ability to - without even trying - place
almost as much spin on their FHs as their BHs (Stokely and Witman are two that I've known...and I'm sure there are a few others), but these are rare birds. For most people, it's a 1:1.5 ratio. And this is the reason that BHs tend to be a "better choice" for tunnel shots (where you need a very straight shot for a long ways). It's all about spin = stability son (said in my best Foghorn Leghorn).
Unfortunately (for the hard workers who truly want to get to be the best but never will) a lot of it has to do with the natural ability one brings to the table. And work as hard as they can,they'll still never do what some people can do all the time.
That's sports at the highest level(s)...suckith that it may
