Sometimes. I have been in boxing, wrestling and martial arts since I was 13. I have done some jiu jitsu and I think it's for meatheads. You can really wreck people and yourself if you do it long enough. Boxing and mma are two totally different animals. The best mma fighters are stronger wrestlers and jiu jitsu fighters with a strong stand up game as a big plus. The difference being boxing is more ducking and dipping and rolling punches where in mma there are knees down there and elbows and backfists. Connor has to be totally reprogrammed to fight a world class boxer. It's a completely different strategy.
