I think he might actually be the rock, just living a double life. Soccer goalkeeper by day, WWF by night..
If Keller is the Rock, that explains the bodyslam to the Mascot. On the other hand, he should've given Borghetti the People's Elbow. Kasey Kelley, The People's Goalkeeper. IF YA SMMEEEEEEEELLLLLLL WHAT DOUBLE K...is.....Cookin'!!
in the past ive also thought that he looks like the rock. its the way he speaks, they both have the same mannerisms and facial expressions in interviews.
