Saluting after made threes

Matthews has done it all year and I assumed it was his thing. Not sure what it meant. But I'm noticing other people doing it now. Earl Clark just did it and I think I noticed it in the Knicks Heat game too. Are they copying Matthews? When did this start and why?

Hmmm....maybe, when he retires, he could come out with a tangy bbq sauce!
