Their swings are closer to today's swings than those of 1970-80s!

Just a guess at who we are watching:
8:25 Ben Hogan
8:55 Byron Nelson
11:09 Tommy Armour
12:02 Lawson Little
14:25 Gene Sarazen
14:33 Ed Porky Oliver (?)
14:43 Cary Middlecoff (?)

Wonder if anyone can them all. I've spotted Hogan and Nelson.
