The Shield is just a regular ol' heel stable. Nexus Part 2.
I would have like to see them attack heels and faces alike, indiscriminately, if they were truly set to be a "Shield of Justice" or whatever.
but they're just a standard Heel Stable that jumps all the babyfaces.
has the Shield ever actually attacked Cena? I don't remember....
They've attacked Heel's (or attempted to) and Cena.
For the Heel's, they went after Big Show, Sandow and Rhodes, and Alberto Del Rio (mostly Ricardo) when he was heel.
