you're not a coach nor are you an expert on anything, you're just some dude on cougarboard so having a technical discussion with you is not better than having one with my mother in law. I watched both of them play, Takitaki was far more athletic and looked both quicker and faster than Barton. Statistics seldom tell the entire story because different defense ask for different things from different positions. Their stats are pretty close to the same but so what? Takitaki isn't playing next to Hansen so he is dealing with more double teams and teams are going AWAY from him whereas Barton benefits from having a guy better than him on the other side so teams are going AT him giving him ore opportunities to make tackles and plays one on one. Takitaki almost never gets that.
But keep acting as if you know what you're talking about based off of some comparative stats and I'll keep knowing you don't have a clue.
