After watching almost half of the game and seeing where the calls are going, it seems fairly obvious to me that Scott Foster is getting a little too generous towards the Heat (if you have not seen it with the Bulls and Pacers series).
Line opened with the Spurs being a 2 point favorite, yet tipped at a 1 point dog. I am not going to go into too much detail here because all of this is Googable (if that is a term yet) - but when Scott Foster is on a game where the line moves more than two points is a SOLID indicator the team of the direction of that movement will be a winner.
We can talk about all the interworkings of the matchups and psychology of a Game 4, but you are watching this game blind if you think the officials do not matter.
Chalk it up for MIA
