Takedowns might be misrepresenting it. They are more like throws. Takedowns kinda, sorta, but not really hint that you are taking the fight to the ground to continue it. MT throws like leg hooks are an important part of wearing your opponent out.
Honestly, when sparring it becomes very tiresome to pick yourself off the ground and stand back up. It seems stupid, and that it would be easy. But after a few rounds, you get back up real slow and it takes a lot of energy. If you've done it, you know what I am talking about.
