Instant replay and injured reserve will be main topics as the owners consider several rule changes this week. The Bills have proposed having the booth official make all decisions on replay reviews instead of referees. Under another suggestion, the booth official also would be allowed to review all turnovers just as he now does for all scoring plays. "This is a proposal that will definitely, I think, generate discussion, but I think it was directed at trying to speed it up," said Rich McKay, president of the Falcons and chairman of the competition committee. "The thing about our system is we developed our system based on our experience the last time. That's how we developed the idea that the referee would be the decision maker because we felt like he had the best ability to one, talk to the on-field official and two, have complete command of the rules and the application of them." A change to the injured reserve requirements for a designated player would be the first alteration in rules for that list since 1993. Until 1990, IR players had to sit out six games, and until 1993 that became four games.
