Average Point Differential of Last 30 NBA Champs: +7.1

I don’t want to keep harping on this, but more evidence to support the fact that point differential matters. It leads to more wins and a higher seed. And like I always say, #1 and #2 seeds win championships, other teams don’t. 

Now, if someone can explain to me why there’s a discrepancy between point differential and efficiency differential, I will be thoroughly happy.
