Correct me if I'm misremembering, but Weidman landed a grand total of two takedowns in his two fights with Silva. In the first fight, he landed a takedown right away, worked for most of the round and then Anderson got up towards the end. In the second round he shot a couple times and Anderson defended. In the rematch, Weidman got Anderson down for less than a couple seconds, then Silva defended all of his other takedowns in the first round, the fight only went to the ground when Weidman knocked him down from the clinch. I don't even think Weidman shot in the second round. Now, granted I would say GSP has a much better shot than Weidman, but we're talking about two guys of compeltely different size here, I remember GSP saying something to the effect of Weidman dominating him when they grappled.
