upsets like this happen on sunday games all the times. lot of these guys go out saturday nights till 3 am with the teammates. But obviously that doesn't meant bet the dogs blindly...you never know who is doing what the night before.
Boston lost to chicago, doesn't mean chicago is a real team. Without Harden, golden sate didn't bring in their a game and played to the competition. Or they had a fun night out on saturday.
By rule I never play a team when the opposing team is playing the first game with a major player missing, because the replacement and the rest of the teams rise up. In most cases i blindly bet the team without the major player. Used to blindly do this all the time and it cashed over 65% in the past but now with teams resting starts all the time you have to look carefully and be selective.
