Two things:
1) If the C's are honest about this being a tendon issue that needs rest, there really shouldn't be any long term risk attached to playing KG tonight. So the whole McHale broken ankle business and how he still limps today really doesn't correlate with KG...if the C's are being honest...
2) Even though that is the case, I'd still rather not see him play tonight. This team should be able to beat the Bulls tonight if they play well. In reality, this team should've swept the Bulls even without KG. If KG is going to come back, I'd rather he give it at least another week or two worth of rest and come back next round (or ideally, the round after).
