NBA Trend - Home Teams?

Just wanted to check with some of you veteran NBA players on this trend I've seen in recent weeks. I've been playing strictly NBA home teams - except for last night's Miami & LAClipper lines - and it seems like an overwhelming amount of NBA home teams both win and cover.

I'm not foolish enough to not see that being on your home floor naturally gives you an advantage. But it doesn't seem like this is as successful an angle in other sports as it is in the NBA this year.

Have I just happened upon a stretch of this or has this been a trend in years past? An overwhelming trend that is...

Thanks for any feedback you can provide..
