Dallas dropping out of the play in entirely would be the best case scenario now. Minnesota would whoop the Mavs in a play in game. If PHX can make the play in, they can theoretically beat the Wolves if they get their **** together.
POR is only 4 games out, the could honestly make it in. I think PHO has a better shot in a one game series vs MIN, but POR has been great lately and they have a chaotic style that could upset anyone on a given night.
