Anderson has never been known for having elite tdd, but Lil nog and Overeem(back in the pride days anyways) didnt have good tdd at all. Neither did forrest. He almost drags his opponents down, rather than landing a double leg, throw or sweep. He typically doesnt go for the takedown either. He will go for it when there is a struggle for position in the clinch or the scramble, but is typically not successful.
Iv been following shoguns career since the start. He is one of my all time favorites but his takedowns and wrestling is clearly the weakest part of his game, not even close.
He also has a good muay thai clinch of his own, but anderson would get the better of him there and thats not the best place to try and get anderson down.
