Lot's of reasons to do a trade like this.

WHY THE HEAT DO IT: Robinson's long contract gets freed from MIAMI to a team who desperately needs shooters. Richardson is a value contract, who is a great 3 and D player who is a locker room plus in terms of culture.

WHY THE SPURS DO IT: TANK TANK TANK!!!! Lose and save $$$ Plus the opportunity to get some draft picks is always a plus. Waive Russ and life goes on.

WHY The LAKERS DO IT: Guess what, the Lakers suck and they needs shooters, they get two here.

The win, win, win trade is a rarity in this league, but this one really has the ability to do just that.
