For your first question, It's happened before where teams that finished lower in the region got higher seeds than teams that finished high. But that would be unfair because look at some of the regions in 2a. They're not that strong. Also, i dont think there's any limits cuz last year region 5 had all teams go to playoffs, n ithink some regions only have 3 or 4 teams overall. N as for the 0 wins, no i dont think so. But this is just my opinion, nothin concrete
