Basically, there’s just too many flags. They gotta change some of the rules a little bit.
The problem.with the refs is their complete inconsistency.
They selectively choose what they call. They let others stuff go despite it being an.obvious penalty.
The other issue is the game itself.
Too many stops and restarts.
There isn't any flowing action.
By contrast, hockey and soccer are non-stop action.
Then you have the TV timeouts, coaches timeouts, etc
It's a really bad scripted product everyone is somehow addicted to.
