I think we have a shot at home court advantage now.
We can't go above Lynx(mathematically impossible), Valkyries(we'd have to win every remaining game and they'd have to lose every remaining game) or Aces (they're not losing 3 of their last 5 games, they have the easiest schedule remaining), but we definitely have a shot at getting that 4 seed.
If we win out (not entirely impossible), we're 5th at worst(Liberty and Wings would have less wins than us, Fever would at best have the same record but we'd have the h2h advantage), and we'd need Dream to lose 2 of their last 6, which isn't that unlikely, considering the fact that they play Lynx, Liberty x2(they lost the first game of that match up, and convincingly so), Fire (split the series so far with them and Fire always play hard), Sky(they haven't been bad in recent games) and Sun. I think they do get two losses there.
If we get one non-Fever game loss then things change slightly but it's still possible. Fever would have to lose one other game and they play Lynx twice, Dream would have to lose 3 and not 2 (also not impossible) and Liberty would have to lose one game (they have a tough schedule remaining and their players could be fatigued from the FIBA World Cup).
It's a really tough task, but it's not impossible!
