Willie Mosconi
 

Damn little footage of him. Here's a bit from the old TV show "I've got a secret". Watch him run a rack set up for 14-1 (aka straight pool) beginning at 6:20. I wish the camera had focused more on his stroke than on the balls going in, but some was revealed.

I remember watching that Wide world of sports, where he, and "Minnesota Fats" dueling for bragging rights, with Howard Cosell announcing......good times in 1978 !

If I recall correctly, all the bragging was done by Fats while Willie easily beat Fats in several of the games played at the time. This was shown when Willie had been out of competitive pool for over a decade...
