What’s a G.A., you might ask? It’s a graduate assistant, and they are generally unpaid (or very poorly paid) wannabe coaches fresh out of college who do all the things the coaching staff doesn’t want to do. Bill Murray’s son, Luke, just joined new coach Sean Miller as a G.A. at Arizona.

What does Murray bring to a basketball program? I have no idea. Presumably, neither does he; he only graduated college in 2007 and is still a G.A., meaning he’ll be doing quite a bit of quiet learning — preparing tape, taking notes, keeping the clipboard handy, that sort of thing — for at least a few more years. But he’ll be interesting to watch. If he has one-tenth of his father’s charisma, it’s only a matter of time until he’s a major college hoops coach on his own.

Good luck to Murray in his new endeavor. Something tells me he’ll do just fine.
