I agree with the head to head penalty. There is a difference in purposely hitting and incidental contact. While we're addressing penalties. Lets look at defensive pass interference, illegal contact, & defensive holding. All three are automatic 1st downs. Pass interference should be maxed out at 15 Ted's. Holding & illegal contact should only be "replay the down" penalties.
Offensive holding, I'm actually OK with.
Good points. Personally, I abhor the defensive penalties aimed at the secondary. You cannot even touch a guy!
