If yall could get all the training you could get in one or the other (ONLY ONE), would it be ground game or stand up/striker? Yes, you can train in both obviously but i am asking theoretically its one or the other. Which one and why?
I've trained and taught for over 20 years. In my experience and those I have trained and/or trained with it is an easier transition from standing to ground. Ground guys, wrestlers, etc can learn stand up in a fair amount of time, but I do believe it is easier to make the transition to ground fighting for stand up guys.
If I could learn only one it would be stand up without question for the simple reason that it is more effective against multiple attackers.
