Check out the remaining games for the top 3 seeds, make your predictions, and see if the Clippers can get #1. Don't forget to make the same prediction on each schedule when the teams face each other

These would be the teams final records assuming the same home and road win percentages:
San Antonio: 18-4 (64-18)
Oklahoma City: 17-7 (59-23)
LA Clippers: 16-5 (59-23)
So the #2 seed definitely looks achievable for the Clippers, but OKC already has the tie breaker, so the Clippers will need to beat their record to get the #2 and HCA in the second round assuming both them and OKC beat their first round opponents.
Spurs need to go 13-9 (.591) or lower in order to be at 60 wins or less. Clippers and OKC will most likely need to win at the least 60 games to get #1, and that's best case.
