Re: Last 4 men standing at the Royal Rumble..
Ziggler, as the last person eliminated by Cena and to keep a big heel in the mix towards the end.
Sheamus, because he is the other big babyface most of us hate but is getting pushed hard.
and I put Other just because it'll go to a heel as it is usually balanced out that way (two heels/two faces). It isn't always that way, but it is a safe bet usually. So yeah, Barrett, Cesaro, any heel.
Ryback is another possibility for the final four or even the winner, but I think The Shield will eliminate him from the Rumble.
