Little risky picking this early in the day but won't be at my computer into the evening (going to Rider's National Logic/Girl Scout cookies game -- see my NCAAB pick), so it is what it is. The Celtics just ruled out Marcus Smart, and while he's not close to the team's best or most important player, he's a very good defender and Boston on average is nearly 5 points better per 100 possessions with him on the court. The Sixers are down Shake Milton and Danny Green but that's not a big deal. Philly has won five straight at home in the series.
