I think what makes Jake so impressive is his ability to just "explode". Only thing, when he does it uses up so much of his energy. He did it against Kampmann and somehow Kampmann survived and ended up finishing him later. I think the Jay Hieron fight he was very hesitant to explode (because of what happened his past two fights Diego and Kampmann, he got tired) thus the reasoning of why his performance wasn't all that great. But he proved to everyone he can go three rounds, so I guess he made a little gain
