ok i think ive figured this out. cbs order 4 new drama's. right now we need the unit to be cancelled and we are good for tar12 in september since jericho was cancelled according to tvguide.
the open slots would then be tuesday at 9,wed at 8,thursday at 10, friday at 9 i think this would leave tar its spot on the schedule. shark is moving to tuesdays at 10
