I actually think it is a bad move to toss Carter from the NLWC. It is almost like an admission of guilt. "Yes we knew you were shady during the season, but no one else knew, so it was fine. Now that this has come out publicly, we don't want to be associated with you!" They literally knew he was an alleged criminal during the season and were fine with it!
