Well considering the team is doing alright without him, you bring him back when he's ready. If Chicago is sitting at the 4 seed and Rose is ready to go mid Feb - why wouldn't you bring him back to make a run at a Championship?
I say play him when he's ready to go. We still don't know for sure if we still can contend might as well try rather than waste a year. It's not like we will be bad enough to. get a decent draft pick. I would be happy if we just knocked off the heat and didn't advance any further lol
