Shame that Orton is injured, maybe he should have been kept on ice for just the PPVs. In saying that he should still be fit for WM if it is just a concussion.
The replacement is a joke. Why not give it to Justin Gabriel, Hunico, Ted DiBiase etc. Yes they aren't huge names but they are serious characters and I really don't think that a comedy character belongs inside the Chamber. Or why not bring someone over from RAW to put in the match.
Or, and this is so crazy I probably shouldn't bother writing it, but why not show some creativity and debut a guy from FCW inside the chamber. Lock four guys in the chamber have Bryan start the match and then have a pause while people speculate as to who the last entrant is. Then out comes Dean Ambrose in his WWE debut. He and Bryan then put on a five minute wrestling clinic before the next guy enters. Let Ambrose survive for a bit and then he can be eliminated, would be a good debut if he manages to hold his own with the World champion Bryan for five minutes. I think that debuting a new guy would be better than a comedy entrant.
