Pregame dunking - is it being well enforced?

[bearclause]

I know it's illegal under NCAA and NFHS rules, and I have seen it called before. I noticed the case of St Mary's getting called for it last season against Gonzaga. Still - I've seen it go uncalled more often - and sometimes even when the officials are on the floor although the dunking typically isn't all that demonstrative. Some people are even posting video that they've taken of pregame dunks. I actually thought that maybe the rule on pregame dunks had changed, but I didn't see anything.

I remember once seeing a pregame ritual (right in front of the officials) before the CIF state championship in Sacramento where one team was alley-ooping it repeatedly and getting within inches of the rim by dropping it from just above the rim. A coach I know who saw it thought that it should have been called at least once for breaking the spirit of the rule.

I understand that there's not much that can be done if the players come out before the officials take to the floor and can witness the act.
