I knew someone would make a thread about this. If you pay close attention, Joe Rogan eggs him on to call out Sherk. It's not like Din called out Sherk on his own will. If Rogan didn't ask him about it, he might not have even mentioned it. He was talking about something completely different and then Joe asks if he's ready for Sherk. What do you want him to say? Besides that he's got just as good a chance as anyone else. He is not the same fighter at 170 as he is at 155.
