They'll be teammates again Sunday, if ever-so-briefly.

Dwyane Wade and LeBron James played together for four seasons with the Heat, and were supposed to reunite for the East in the 2015 All-Star game in New York -- but Wade missed the game to rest his sore hamstring.

Wade's healthy now, and was the second-leading vote-getter to James, so both will start.

Plenty has made of what James learned from Wade, about becoming a champion.

But what about the other way?

What did Wade learn most from James, when they played together?

"The biggest thing is, he's one of the smartest basketball players I've ever been around. I mean, I look at myself as a pretty intelligent basketball player. But I'm not as smart as him, from the standpoint as far as his ability to put guys in certain situations. To be able to read every guy's position. It was pretty impressive, how he was able to -- no pun intended -- be a coach on the floor."

Wade laughed as he said that, because he'd been asked the question on the day that the Cavaliers fired David Blatt.

"Like (Rajon) Rondo," Wade continued. "That kind of talent. You know what I mean? You see that play the other night where Rondo put DeMarcus Cousins over there (in a spot). Not too many guys can do that. And LeBron was one of those kind of guys. I was always more impressed with that than I was with anything else."
