Earl was Lefty. 'Nuff said.
Just kidding. Watch WRW bowl and then watch Earl. Their heads NEVER MOVE until they release the ball. And they may be the only two ever who's don't AT ALL.
Mark Roth also had a relatively short competitive bowling career. He bowled full time for about, what, 10 years? Brought Earl out of retirement, so I heard. Whereas WRW and Earl have smooth, accurate, textbook "this is how you bowl" styles, Mark Roth's could be described as "Grip it 'n' Rip it!" And in no way, shape, or form would I EVER tell someone, "Watch Mark Roth bowl and bowl like him." However during his dominant period, was was just as if not moreso than Earl during his.
