Can anyone help me with a question regarding the "K" Balls that the NFL uses? From what I understand, a "K" Ball is a new football setaside specifically for kicking. They cannot be "softened-up" prior to use. Are there any other differences that I'm not aware of? Also, is the NFL the only league (i.e., NFLE, CFL, NCAA) that uses "K" Balls?
