I could see him teaming up with Abraham Washington, since they're both doing dark matches right now.
Mark4: Drew McIntyre, Alberto Del Rio, Sheamus, Wade Barrett, Ezekiel Jackson, Kane, Edge, Michael Tarver, Chris Masters, Dolph Ziggler, William Regal, Zack Ryder, John Morrison, JTG (Ya Killin Me Son).
Rather than having him act like the guy hepped up on goofballs, I say let him be the character that he was in his first teaser promo for NXT. And wrestle as THAT. Dude would get over in about 5 seconds.
