You already mastered the striking game man, I don't see any limitations that you would have learning the ground game my friend. If you put your mind into it you def can do it, the belt system is nice but there are plenty of great fighters that do not have all the belts and whistles lol man training at aka you have the creme of the crop to train with

you are already doing the more painful discipline adding takedowns won't be any worse lol
Let me know if you end up fighting and if there is a feed to see it through ! The united glory fights tonight should be awesome I can't wait.
