Frankie Edgar beat BJ Penn twice, and in an appearance on UFC Tonight said he thinks he has Penn's number, and may retire him.
First of course the pair will coach opposite each other on Season 19 of The Ultimate Fighter.
"I do think I have his number," said Edgar. "Every fight is different. I'm going to approach this as a new challenge. I'm not thinking he's going to come in the same as he did the last two. I expect him to come in and change a little. I want to show my improvement over the last three years. I think he was kind of close to retirement and I think another loss will maybe decide it for him."
What do you think UG? Could Frankie Edgar retire BJ Penn?
