What if the Undertaker was in his place against Seth Rollins? Sting isn't going against Seth because he's apart of The Authority, but because he's considered an all time great and takes offence to Rollins' remarks. But wouldn't Undertaker fit better in that scenario, and wouldn't it make more sense? Undertaker could've argued that if it wasn't for him then Lesnar would be the champion, and that he could've waited until the match was over before attacking him. Instead, he cast Lesnar from the title picture entirely while Seth remains unscathed. He could've also brought up shades from his Big Evil gimmick and say that if Rollins really wants to be seen as a great then he needs to earn Undertaker's respect by stepping in the ring with him. Undertaker could've made Rollins famous. And now we know this is probably his final run, so doesn't he deserve at least one more shot at the gold? I don't know, he just makes a lot more sense than Sting does in that regard.
