Personally, I think it's high-time to scrap the whole preseason thing and move to an 18 game schedule.

Have two "controlled scrimmage" weeks with joint practice sessions against another team(s).

Didn't we do that with Buffalo every year? I remember because it seems like the score was always 13-10, regardless of winner. Seems like a couple weeks like that could get the players ready enough.

Pick two names out of a hat for the Hall of Fame game and call it a day.
