honestly, reem's mma stand-up is wack. he just throws some kicks here and there and looks for the big shot, not much combos, feints, footwork or anything...and to add to that, he has crappy defense (its almost like he forgets he's not wearing big gloves, plus he doesn't have great reflexes) and a weak chin. i mean, his biggest strength is clinch range up against the cage where he can throw knees and elbows and short punches and shyt.
jacare-weidman is cool, i'd watch it. i don't think jacare wins though. he's not gonna be able to take weidman down at will and he'll have more success on his feet than mousasi did. chris controls distance extremely well and at the same time stays aggressive and has power in his hands. if jacare manages to get weidman down, it would be interesting though. i mean, mousasi's guard is awesome, he is great off his back...one of the best in mma but jacare kept passing him and controlling him and had some submission attempts, then eventually took his neck and finished him...weidman's bjj is strong but i dunno if it's that good, particularly in those positions. we haven't seen it.
i'd bet that weidman wears jacare out and has a late finish.
