Tiago as an x-factor: if we can keep him on the court, we win. Simple as that. If he's on the court, it means Miami will be doing minimal scoring in the halfcourt and that we can move the ball against their defense despise having TD and Splitter down low.
Edit: not to say that if he's off the court, we lose. But if we are able to stay with our normal rotation, it means we are playing a game Miami has no chance of winning.
