I didn't do this at the time, but I found an email I sent to a friend before the playoffs started and it's looking good so far (only the Bucks and Pacers threatening to mess it up - who'd've thought it was a mistake to bet against Nate McMillan getting out of the first round):

Is Curry out indefinitely?
Even if so: Warriors over Spurs
Pelicans over Blazers (sob)
Jazz over Thunder (suck it Westbrook)
Rockets over Wolves
Rockets over Jazz (sob)
Pelicans over Warriors (if Curry is out)
Rockets over Pels
Celtics over Bucks
Cavs over Pacers (just cuz LeBron)
76ers over Heat
Raptors over Wiz
Cavs over Raptors (just cuz LeBron, pt. 2)
76ers over Celtics
Sixers to the finals! (Unless LeBron...)
Can the Sixers beat the Rockets? Sure, why not? If Embiid is healthy.
