But, all that activity seems to have resulted in competitive balance. In the first three seasons, 24 of the 32 USFL/WFL franchises qualified for the playoffs.
Just look at the last two seasons.
LAX went from 6-10 to 11-5. Oakland went from 6-10 to 14-2. Cleveland went from 8-8 to 13-3. Orlando went from 2-14 to 11-5. Tampa Bay went from 8-8 to 15-1. Georgia went from 5-11 to 15-1. Birmingham went from 4-12 to 13-3. New Orleans went from 7-9 to 13-3. NY Stars went from 1-15 to 10-6.
So, it can be done, and it doesn't take 10 seasons to do it. Hang in there, read the forums, ask questions. You'll get there.
