Jim Ross was recently interviewed on the Two Man Power Trip of Wrestling podcast in which he discussed his thoughts about Seth Rollins as WWE World Heavyweight Champion, claiming he shouldn't lose the Championship until WrestleMania 32. 

"I would not take the championship off of Seth Rollins until WrestleMania. At WrestleMania, if I have something that I believes works, then that is where he would drop the title. By then he would have had a full year and if he is not over and he is not a 'made man' after being champion, then you can't blame the promotion."

"I am very proud of the worker that he has become. He has a great mind for the business. He is a booker's dream; in other words, he is a beatable champion. In the territory days or the live event days ... theoretically on any given night that he is defending the title he can be beat. He's not so physically imposing that he looks unbeatable and I like that. If you are going to have a heel champion then I like one that has vulnerability."
