Datone Jones took Martial Arts Training seriously, he got his reps in and made it work on the field. 26th NFL Draft pick to Green Bay, 2013....this stuff works. 

"Gets his hands inside his opponent" "Pushes forward with a violent strikes" "Impressive array of hand moves to get through"  - Yahoo Sports

"Reportedly, Jones has been working in the offseason with MMA trainers to improve his hand usage, and the results have been fantastic. He regularly used his violent first step, not as his primary weapon, but as a complementary element in his skill set. I saw him neutralize punching hands, throw down textbook swim moves, and generally just look more complete as a pass rusher than I have ever seen him up to this point. The highlight of Tuesday’s Senior Bowl practices to me was Jones being the only defensive player to beat potential top-10 offensive tackle Eric Fisher. Using his deadly quickness, he jab-stepped hard to outside before knifing back in on a great club-swim and gave himself a direct path to the quarterback. It was a beautiful move and the proof that I needed that Datone Jones is more than what he showed at UCLA."

"I threw a punch at him and he grabbed my hand, flipped me to the ground and acted like he punched me in the throat," Jones said. "I was like, 'Ah, man, this works. I'm a believer.' "
