Like others have said - officially out. Here is why:
PHX has an upper limit of 52 pts. Since Minny now has 53, only the 8th spot could be in play for PHX, so they have to pass all 3 of Dal, Det, Cmb.
Now, let us first consider Dallas' schedule. They have games with both Det and Cmb. If they win both, they end up with 52 pts, and they would win the tiebreak with PHX. That means that either Det or Cmb has to beat Dallas for PHX to have a chance.
Now, Columbus. If Cmb beats Dal, Cmb ends up with 53 points, so PHX would be out. Therefore, Cmb can't beat Dal. In fact, if Cmb wins at all, PHX is out.
So, finally, Det. Det has to beat Dal. But, Det also plays Cmb. Cmb can't win any games, so Det has to beat Cmb, too. Thus, Det ends up with 54 pts, and PHX is still out.
I know that's complicated. But, it all adds up to: with the schedule the way it is, no chance for PHX.
