The jab was fine. In fact, if he used the jab any more, he would never get another fight lol. Promoters like action in these 4 rounders. As far as the fight itself, I think he exhibited solid instincts overall and maybe got a little tired in the last 2 rounds.
Haven't seen the video, but you shouldn't try the shoulder roll unless it comes naturally to you, it's very easy to pick apart a guy forcing a shoulder roll, copying mayweather...
