re: So what are the realistic odds we see Zion this season?

I think they are ramping up to play if we get through to the actual playoffs. We have little chance at beating Phoenix as currently constructed. Throw Zion in there and maybe we catch lightning in a bottle. That would be 10 days from now. It's doable if we are to believe he is getting close to 3on3 and eventually 5on5.
It would also be considered a compromise that Zion and his camp could agree to.
