Mack should really improve on combo punching, if so he could've had Henry out earlier, Mack's got potential but he has a long way to go if he ever wants to win a title, at least he's a top 10 fighter now though.
Both of these guys are B-level.. I almost want to call Henry C+ level. Mack has no stamina.. and Henry is just persistent.
Mack has more potential, he has a very good right hand, and if he can get his combinations together and get his stamina right he can be a world champ. Henry needs a fighter who can't stand to be pressured and a lucky shot to become a world champ. There's the difference in the two.
