Well, to meet you half way I did try to make sure I had the full context of the argument before jumping in, but in reading back further it was more of a "who's more comfortable in possession?" conversation than it was a "who's a better defender?" discussion. If that's the case, I have a lot more sympathy for someone being a bit more absolutist about it. You could find a one-legged monkey smoking a pipe who looks more comfortable on the ball than Mangala. Just becomes a more nuanced discussion when you start to value his lack of comfortability on the ball vs. not lunging into tackles all crazy-like, getting passed by simple 1-2's and giving away dangerous free kicks.
Anyway, Laporte... bummer for us. Still theoretically happy in the end if I felt like that money/attention was now going to fullbacks.
