They can still have Daniel Bryan lose at EC and get into the WM Main Event pretty easily,lMO.
Have Randy Orton win the EC to go into WM as champion. However, make DB and Orton be the last 2 in the Chamber, and have Bryan screwed by Batista(who turns full heel and is angry at the Bryan love). Post-EC, Bryan demands his inclusion in the Main Event. Long story short, he gets placed in the Triple-threat everyone talks about. Job done.
Yeah, pretty much. I can't see the EC match ending clean. I'd be shocked to see if Orton wins without interference like he did at TLC against Cena. History shows his wins are flawed.
