To be an NFL Referee...

[FRPLG]

I think if some things are challengeable then everything should be challengeable. It is toally inconsistent to have the ability to overturn some calls while not others. Every call can cost a team a game and to say basically that you trust the officials to make some calls but noth others sounds ludicrous.
I think there also needs to be something done about this crap where they decide to arbitrarally enforce some rules and not others. Why the hell have the chuck rule for a decade before you even start to enforce it? Makes no sense at all.
