I can't say I'm wowed at the prospect of Show/Lesnar again. I am a little surprised WWE expects us to take Big Show seriously as an opponent for Brock after having him dancing in a diaper throughout both Raw and SmackDown just a couple weeks ago.
I don't know if Lesnar/Langston would've been any good, but at least it would've been something new for Lesnar to do. Hell, it might've even made a star out of Big E.
