Half the unnecessary roughness calls are...well unnecessary. Everytime there is a key injure in the NFL, they tighten up their rules when it comes to tackling. Like look at the "Tom Brady" rule. Its football, you're gonna get hit. If they don't like it, they should work a 9-5 job like the rest of america. Back in the day, football stars made not much more than me and you, and they all played 3-4 different positions. Somehow while football is still good, its becoming less and less appealing. People watch for the big hits, people watch for the struggle. and its all slowly disappearing.
P.S. Go Packers!
