It would make sense if a newly crowned champ gets to call his or her next fight. A revenge fight (Bisping v. Hendo) a money fight (Woodley v. Diaz) or just someone scalp that they want to try and take next. After that Champion's rights fight, defend against the #1 contender. All call outs must be currently on the roster and in the same weight class and the belt is always on the line. Victoribus Spolia aka the salt shaker rule.
