[I was a pitcher in my younger days, and have perhaps thrown a dozen or fewer perfect knuckleballs (out of hundreds of attempts), but Ill never forget what it looks like. Your jaw drops because its hard to believe what your eyes have just seen. I never had to try to hit a good knuckleball pitcher.]
I used to help train my younger brother in high school,he was really pretty good. A good knuckleball is a sight to behold, a bad one sails over the fence.
Ain't it the truth. And the difference between a decent knuckleball and a bad one is slim. Just a 1/2 a rotation or so.
