Predictions can be and often are tricky things. Just ask the meteorologists who anticipated a historic blizzard would strike New York City in mid-March, only to see Winter Storm Stella drop a sane seven inches of powder on Central Park.
Bleacher Report doesn't ask its NBA experts to forecast the weather, though preseason prognostications are well within their purview. But even B/R's brightest basketball minds couldn't come up with perfect prognoses for the 2016-17 season, no matter how many tea leaves they read or stat sheets they pored over.
And, really, what good are these kinds of educated guesses without some measure of scorekeeping after the fact.
