I probably see as many MS coaches as anyone here, and I can tell you I think there has been a deterioration of professionalism and behavior over the past few years. Of course, this is a broad (Juulie - I don't mean it
that way) generalization. There are still many who act professionally and don't cause problems, but not as many percentage-wise as in the past, in my opinion.
The only reason I can come up with for this is perhaps there is a higher level of success expected by upper level coaches for whom these MS programs act as feeders, and by parents, than in the past. As I'm sure we all agree, parents equate yelling and screaming coaches with effective coaches. Plus, they may also be trying to deflect blame for lack of success so the perception by "higher-ups" is that they aren't as bad as they really are, when being considered for promotion.
Or, maybe our society is just producing more jerks who want to coach. Yeah, that's it.
