In the related Tribune article by KC, he mentions that IF Jo were to start, it would be for Niko. I know some BaB'ers would hope it would be for Pau.
I'm guessing we won't know the answer to this until tonight. However, if Jo gets the start tonight, it will be interesting to see how much faith Hoiberg has lost in the Pau/Niko combination going forward.
On a somewhat related note, the Bulls seem to be believe part of their defensive problems are due to communication, or lack thereof:
"(Sunday) was a good step in the right direction toward … guys talking to each other," Hoiberg said.
