170 Maia? I hope giant Chris Weidman could just lay on top of any 170 fighter.
No they fought at 185. Maia and Jacare are 1 - 1 in competition bjj but Jacare had some pretty freakish explosiveness back in the day and I feel that that's starting to go. Maia pulls half/full guard all the time to work his way to the back whereas most of Jacare's work (that I've seen anyways) starts with him getting the TD and working to pass on top. Like I said I doubt Jacare can take Chris down and think that if he was comfortable in Maia's guard he'll be able to handle Jacare's as well. If it stays on the feet I think Chris is better there also.
