I hate going totals with the 76ers, glad my bet is done with - had them FH -5.5. I run into the same issue with the Celtics and totals.
What's wrong with the 76ers totat? Sometimes they scored low, sometimes they scored high.
That's the norms of the game it's very unpredictable, and I'm telling you, even if you use some statistics, it will still not guarantee anything.
