you have to figure out why your doing this.
and dont give some BS answer really think about it and be honest.
Your and your friend thing you guys will be cool? your and your wrestling buddies think you can start a new fight team, get all the ladies and all that?
That might not be your reason but what im saying is i would never put myself in a ring to loose, yes anyone CAN loose but you need to make sure that if you do its because the guy was just a all around better fighter OR better that day.
I have been training for awhile now i have coaches and trainers and guess what? they dont decide when i fight, i do because i want to win or at least go out with such a good fight people want me back.
i think personally you COULD win this fight but it will not be impressive more like luck, and why would you want that? You NEED to be ready and you NEED to do it right so you can go in there and look the part. My friend from my gym had his first fight against someone just like, you. They are called "independents" they have no fight team nor gym they just watch it and teach themselves and go for it, and believe me my friend kick his ass, you could tell this guy was just waiting for the fight to end, and after, he put all sorts of images on his website bragging saying oh here im going for an armbar or here i was about to do this, blah blah blah.
See thats all he wanted out of it, but what do you want?
because if you want to fight for a lone time, and do it right then you need to back out of this fight, find yourself a coach and gym and try again it about a year.
Im all for people fighting i love this sport an ill help anyone i can but one thing i canst stand is people that do it half ass just so that can say that they did it. Whats the point?
Good luck and i hope you take some of our advice.
