Colt Cabana might have taken a shot at CM Punk on today's episode of his podcast with Christian.
He talked about wrestling Ryback, and he said "And, there was a time on this podcast where Ryback was talked down upon, but I basically said 'Okay, you're here to tell your story, you don't need to really bash the guy like this', but he was great about it, and he handled it really well".
So, this should be taken with a couple of fistfuls of salt, and it could be that Colt is thinking "Fuck this guy" and is saying it because he's still pissed at Punk, but it does seem like he thought that Punk took the Ryback shit way too far.
