The system has been this way forever. (Taking out the fact that we were once in a BCS conference) the Mid-Majors/non-BCS/G-5 have always had the advantage.
I'd argue a team with a loaded schedule out of conference could have a shot of crashing the party.
Also, there will be a day of expansion, and the G5 will get its place at the table. That's why they're not burning bridges now.
Finally, It didn't seem to bother anyone when we were in the BCS...
