Reminding me of a play I saw on the Red Zone yesterday, Oakland defender trying to break up a pass was initially flagged for a personal foul ('defenseless receiver') which looked like a BS call. Red Zone went away from the play but it looked when they came back that the refs talked it over and picked up the flag.
Just to say, these games are changing. I don't know that I like the changes, although I'm not against player safety. There needs though to be some consistency, fast, not only in the rules but in the application of penalties for infractions, and then we can adjust better to the changes, whether it's to accept them and get used to them, or find something else to spend our leisure time following.
Who knows, maybe in 15 years the pucks will be foam and the sticks will have the hardness of pool noodles... not sure I'll still be watching but...
