Question for you multi-sport officials

[Mark Padgett]

Over the years, one of the things we've discussed are the differences between basketball rules at different levels. As we all know, there is a multitude of differences between NF and NBA. For those of you who also work baseball and football, do you think there's more differences between HS and pro (not semi-pro, but NFL and MLB) in either one of those two games (or both) or do you think there's more differences in basketball.

I'm just curious as to which of the three sports would take the most training to move from calling a HS game to a pro game (not that it's actually happening). Thanks.
