Why waste my time?   We’ve heard for years the refs are gonna get better and nothing changes!   Is a ref supposed to talk to fans in crowd?   I don’t care how long they’ve been calling, they still do it.   Even had a guy from other team that was sitting in front of me that is a college ref that said the refs need some education on interacting w crowd. 

Also, if ref stops play for “injured player” does that player have to be substituted for?
