If the CW folds, WGN-TV would simply go independent. They were a successful independent for nearly 40 years before joining the WB in 1995, then CW in 2006. Going independent would allow them to not farm out weekday sportscasts (unless 2 sportscasts air at the same time) to WCIU. Primetime hours with no sportscasts would either have movies (like prior to 1995), or they could have off-network syndicated shows in primetime.
