Refs are overly involved by design. Rules are left ambiguous by design. It's not a coincidence how many primetime games end up being decided by last second field goals or go into OT. The NFL classifies itself as an entertainment entity, the same as the WWE does. The refs are doing what the leagues wants the refs to do which is to manage the games. The Chiefs / Bills would have been a blowout by the middle of the 2nd quarter had the refs not managed it. Anybody deluding themselves into thinking any of this is isn't by design is a fool.
