I like that the 15 yard penalty for targeting can be removed after the replay.
I don't know how I feel about the roughing the passer rule. It is designed to protect quarterbacks, but it is football, and players just need to play and not worry so much about where they hit a guy, as long as they are not trying to injure someone.
I always thought this was reviewable?
Watch for more unsportsmanlike calls this year.
