Here's Dabo Swinney's bold idea, as told to the Atlanta Journal-Constitution:
College football teams have the option of a spring game against themselves or another team. If you play another team, it must be both an out-of-conference team but also one within a reasonable driving distance. The coaches will agree upon the rules of the scrimmage in advance.
The NCAA would have to sign off on this plan, of course, but I think this would be very popular.
