1. Chop blocks, roll blocks, downfield cut blocks, and peel-back blocks, which can injure defensive players.
2. Protections for read-option quarterbacks while in the pocket.
3. The hands to the face penalty, which could expand to encompass quick blows to the head in addition to the current prohibition of pinning the opponents head in a sustained manner.
4. Low hits on defenseless players, specifically receivers while catching a pass.
5. Taunting and fighting penalties, to ensure players are treating each other with respect.
6. The point-after touchdown, which could be eliminated.
7. Playoff expansion, which would add a No. 7 seed in each conference, eliminating the bye for the No. 2 seed in each conference.
8. The instant replay system, which could be adjusted to mirror the college system (where the replay official makes the decision) or to adopt the NHLs approach of centralized review.
