This is a make or break game for OKC. Might as well be an elimination game imo. 3-1 is too big of a hole for any team to hope to come out of.
And as for the argument that I started a few pages back about free agents going to Miami if Miami wins, and that is still an if at this point then players will be looking to go there to get a ring, and there should be no doubts about that. Most of the good free agents this off season (that are in the category of ring chasers) play PG and C, coincidentally that is Miami's two weakest spots. Where as OKC has a great PG, and a very good C. If you want to play the game, and have a chance to win which team is more appealing if you are a PG, or a C. The obvious choice is Miami.
Then we bring in non basketball reasons like the no state tax (they may pay income tax based on where they play each game, but playing 50% of your games with no income tax is better than playing 10% of your games with no income tax), the nightlife, the weather, etc then you are looking at a much better spot to play.
I haven't crowned Miami yet, but if they do win this title, and nab one or two of the free agents I listed they will repeat.
