The only thing Christian Cage accomplish in TNA was being the 2time NWA Champioin. In my opinion the only reason he didnt get a title shot in the WWE was because he didnt earn it and he started to slack off ever since him and edge isnt tag team partner nomore. In TNA they felt sorry for him so they made him the Champion. The sad part about this is that Edge his own brother is doing way better than him. Christian should come back to WWE
bullshit since he had his title shot just before leaving, he could have been main eventer now;
In TNA they didn't give him the title because they felt sorry(that's ridicolous), but it was probably a clause of the contract to convince him, i think Angle has too.
As people above said, Edge is not is brother... then why sad? Edge is the most deserving champ in the last 3 years.
Last i think that he could be good in both WWE and TNA, the problem is in WWE due to his size it will take more before he could be considered again ME material
