I think #14 is a really good one. So often the wrong guy gets flagged for a personal foul during an altercation.

14. By Washington; to amend Rule 15, Section 2, Article 4 (Reviewable Plays) to subject personal foul penalties to Instant Replay review.
I think #6 is probably directed at Bellicheat in New England for declaring people eligible as receivers at the last min. If approved they will have to send them out with a vest with a number on it.
