Whoever said “All publicity is good publicity” never met Stephon Marbury, the basketball player (I’ll avoid using the term “star”) who defended Michael Vick.

Vick, as you might recall, is in all kinds of hot water because he likes to see dogs fight. That kind of obsession can lead to the cancellation of your football career, lucrative endorsement contracts, fines and jail time.

If any time is the time to keep your mouth shut about defending Michael Vick, this would be a good time.

But Stephon saw this as an opportunity to get his name in print — and did so just as he was promoting his own line of basketball shoes.

I’m sure his sponsor is having his lawyer review the sponsorship contract now.

Lesson learned: Watch what you say, when you say it, and be careful about hitching your wagon to a locomotive going downhill.
