I'd go with TBK as well. Can you imagine him waking down to the ring, bouncing around in that girly way he does, with the WHC struggling to stay around his waist, squaring off against someone like Batista, and then retaining? I'd laugh throughout the entire reign, loving every minute of it.
It's not that he's a bad worker or has an attitude problem, it's because he won't stop smoking marijuana apparently. Everytime i read a report about him on WZ, it's the same story. Talent that get caught with weed in their systems get fined, and TBK doesn't care about fines, so they punished him by ending his push. Hence why he went from #1 contenders matches to jobbing to higher profile jobbers. He probably thinks, i get paid more than i ever thought i would in WWE, even as a jobber, so i'm happy.
It's the same thing with Shelton Benjamin. He doesn't bother to go all out all the time, or improve his mic skills, because he's already made more money than he ever thought he would when he was still in amatuer wrestling, so he doesn't bother sticking his finger out, and therefore he doesn't get pushed.
In an interview with Ken Kennedy, he said that he know wrestlers who smoke a pound of weed a day. One of them HAS to be TBK, and for that reason, he'll never rise above the mid-card/jobber level, despite having a cool gimmick
