You will need some teams from 8a to get that 5th win. Even putting GW at 4-5 and St. Iggy in there as well. I counted 26 with 5-4 records you would need at least four more teams to punch there ticket to get E-Ville to 7A.
The only way this works is if they combine two levels together to get the travel down. Pair 8 with 7, 6 with 5 and so on. Its not going to be perfect but It is the only way i see it actually working.
