Top 10 UFC fighter (not just top 10 of his weight class, top 10 overall) at his physical peak (in the middle of a fight camp) and with a "I'm willing to kill and/or die to win this fight" mindset has hell going hands on with a mentally ill guy who broke into his home despite outweighing him by 20-30#.
It took every bit of his size, strength, cardio, skill and mindset advantages just to drag it out into a stalemate until LE arrived.
Really good reminder that an inaccessible gun might as well be on another planet and that it's a bitch digging yourself out of a initiative deficit, especially against a committed and/or crazy opponent.
