He was promptly scolded by old-school coach Scott Skiles. Skiles and the Bucks claimed it portrayed a lack of focus.
Then, a couple days later, Shaq comes through with a post of his own at half time. His coach, Alvin Gentry, didn't seem as concerned.
I really don't see what the difference between posting a comment on Twitter or stopping to answer a TV reporter's questions. It does symbolize a start of a shift to giving an update to your fans and friends, rather than to the general public. It creates access and intimacy among your followers. I think we'll get to a point where college coaches are posting updates (or maybe one of their assistants anyway) during halftime, pregame, and postgame, as it will become a way to show off your style and your adjustments to your fans, recruits, and players' families. It will create a family atmosphere. It just needs to be done in a way that doesn't make you feel there's a lack of focus.
