I think you have different answers based on the game. Of course Buddy probably had the best rock in 9B.
When it came to "short-position" in games like 14.1, I don't think I've ever seen anyone with tighter control than Hopkins and Sigel.
So, it's hard to pick ONE guy generally speaking since there are different games and Buddy, although he had a tremendous CB playing 9B, he wasn't as tight in games like 14.1.
So I consider "best shape" to not only be "having the correct angle," it's really how close to the CB you are with the correct angle.
I know there are tons of Buddy fans and I'm his biggest 9B fan; but if Buddy in his prime played Hop or Sigel in their primes in a 1000 pt 14.1 game, I don't think it'd be close.
