I was in the 53-55 range before the trade and am settling into 55 wins as my prediction.
Being behind on chemistry is a concern for a slow start, sure, but our schedule is very weak early in the season. Up through Dec 31, we play:
Elite teams: Cleveland x1, GSW x1, Houston x1, Spurs x2, OKC x1 (6 total)
Next level of good playoff teams: Toronto x1, Washington x1, Minnesota x0 (2 total)
Next level of playoff to fringe playoff teams: Milwaukee x3, Charlotte x2, Philly x2, Miami x3, Detroit x2, Portland x0, Memphis 1x, New Orleans x0, LAC x0, Denver x1 (14 total)
Lotto teams: NYK x2, Magic x2, Hawks x2, Pacers x2, Nets x2, Bulls x2, Utah x1, Lakers x1, Mavs x2, Suns x1, Kings x1 (18 total)
I'll make up some arbitrary percents that we think we'll win of those games, say we'll beat lotto teams 85% of the time, next level of playoff-fringe playoff 70% of the time, good playoff teams 55% of the time, and elite teams 40% of the time. That would give us a record of 29-11 through the end of December. That's a 0.725 winning percentage which would be on pace for 59 wins. But our second half schedule gets tougher which is why I'll settle into 55 wins.
