Thanks to John Hollinger everyone can stop thinking... http://sports.espn.go.com/nba/columns/story?columnist=hollinger_john&page=PERDiem-090414
Good point I didn't really think of it that way but I do agree the worst 2 scenarios are with a HOU loss.
I would like the 3rd seed first because it would move HOU to the Lakers bracket. Secondly it would cause an LA matchup to be in the WCF on a higher stage. Playing LA in the second round will be premature and cause the WCF to be a bit of a letdown, from my personal purely theatrical point of view.
To simplify the complexity to its essence: If San Antonio wins, we must win to preserve home court. If SA wins and we lose, we are the 5th seed and lose home court advantage in the first round.
