I would still like to see 53 men dress on Sunday and let teams use their practice squad as their "minor league system." When Jimmy Ward gets hurt, there's a guy on the PS who plays safety can replace him. Having 46 guys dress is insanely stupid. (but i guess they do it for MINOR financial reasons.

I still think holding calls should be 5 yards--defense AND offense. However, on defense, it could result as a first down after the first infraction of the current drive. Get two defensive holding calls on the same drive--the second one will result in an automatic first down.
Coaches should be able to challenge during the whole game. The fact that coaches can't challenge during certain parts of the game is f**king retarded.
Penalties should be reviewable. Sorry, but this speaks to the incompetencies of the refs.
Refs should be full-time employees--absolutely no exceptions.
Move the KO back to the 30-yard line. I know their reasons to move it up but the game seems faster my way.
