Learn to wrestle!
Simple fact: if you want to be able to stop a wrestler from taking you down, and cracking your head open in a street fight, you must know at least basic wrestling. Otherwise, you may think you can stop a takedown, but trust me, you can't.
Don't mix up stopping your friend, who never wrestled in his life from taking you down in class, while executing a crappy, made up, and low level takedown, to stopping an actual wrestler, that lives and breathes takedowns. You're only fooling yourself.
Train smart,
Stay safe,
