Big Nogs biggest weakness? His Physicality. Nog has always looked lumbering, Slow and lacking explosivnessness... His Boxing was technically good (apart from lack of head movement) and his BJJ was about as good as it gets at heavyweight.
In this Video it shows how he has been working on his Speed and explosivness...
I think some of the older generation of MMA fighters got by on not using modern training methods, YOu see some Standard training in Gyms, Hammers hitting tires, Elastic to that makes it harder to punch etc.. I dont know if old school fighters like Nog were so big into strength and conditioning training.
After hearing how behind the times Crocop was with his training I think Perhaps Nog was in the same Boat. Now he is working on his weakness I think there is a really good chance he can be a title contender.
Theres a part at about 2mins were he throws a straight at the Heavybag and the Speed and Snap on it is like nothing ive seen from Nog before. I really hope he gets back on track and gets a rematch with Mir.
