I have read alot of opinions about Boxers getting into MMA fights. I agree they would have a hard time perfecting a ground game against someone that has been working on theirs for 20 or more years.
The thing I havn't seen much of is people talking about MMA fighters taking on a boxer in a boxing ring.
I think the same thing would happen. In my opinion, a top MMA fighter wouldnt hold a candle to a club fighter.
It's just not the same skills.
