Boxers who should have done mma?

Why fighters out there would have been better in mma due to their styles? I think maidana would have been from his pressure and fighting style I also think he would have been pretty good with his kicks but ground wise he'd Prbly get beat up Vitali I think he would done well also just if he ever got to the ground he'd Prbly be in trouble because of his height but his ability to mount you with those long azz legs would Prbly help I think jack Dempsey would have a shot too being he's strong big legs good for kicks and incredibly strong good for takedowns plus he was aggressive so I could see a lot of knockouts What's your thoughts?
