Re: The spread of pinching rollers this year

For added security, at Long Beach, 968 added springs to actually push the ball into the ground with some force, beyond the weight of itself and the mechanism. I don't feel that any team with such a mechanism got away with a certain "way" referees were calling anything.
I was under the impression that 233 had a mechanism that oh so slightly lifted balls, and that caused them to miss elims at Florida.

I doubt refs ignored this when I've read posts about how teams were pulled to practice fields to prove balls stayed on the ground.
