Game Management?

[Almost Always Right]

In most of those sitches, one team is probably playing man to man and the other sits back in a zone and is not as aggressive. This has been my answer to coaches before, " . . .coach you are more aggressive than they are."

In these sitches of course you are going to have a foul discrepancy however, if both teams are playing aggressive defense, you have to be consistent on both ends and part of that is being aware that your partner(s) are calling hand checks, illegal screens, etc. That is in part where this type of philosophy comes from. It does give the crew an air of consistency, regardless of whether they are or not.

IMHO - I do my best to just call each play and hope that I am aware of what my partner(s) are calling or not calling. At some levels, we are trained by people that control our collective destiny that the foul count should be as close as possible. Most of the time it works out for us.
