Like most, if not all have said already, if they are both out for a short time, The Game comes back, to an extent, and Sheamus is pushed more. I could see Bryan getting the green light on Raw and feuding with Triple H. But, if they are both gone for a longer time like half a year or more then more is going to have to be done. Triple H. could come back full time, Maybe more old names come back like Batista, John Morrison could be brought back and given a big push. Bryan will be one of the top guys for sure and Sheamus and Barrett could rule Smackdown. Can't forget Dolph and Cody. Maybe they would finally get their big pushes to the main event level. I personally think they will both be winning MITB this year with One cashing in early and the other later in the year, maybe wait til Mania 29 and a new star is born. If Ry Back ever gets to face real competition I can see him moving up the ranks pretty quickly, as long as he doesn't hurt anyone. If they really wanna make him a big star have Ry Back take on Lesnar at Mania 29 or Goldberg, and have him destroy his opponent. Basically, there is a lot of things that can happen if these two guys get injured.IMO. WWE just have to make good story lines and bring back or create new stars. Easier said then done, I know.
