Jack does deserve credit for the win. He came in with the better game plan and executed it well. He started off with a measured pace and upped it in the latter stages. His body work was very impressive, you could hear them thudding in from the 7th round onwards and that clearly in part took the wind out of Groves. The knock down in the first round showed that he's smarter than given credit for. The first right hand hurt Groves, Jack then feinted to see what Groves would do, Groves tucked up behind his guard and so Jack threw an overhand right instead of a straight right to go over and around the guard. Jack is an entertaining and improving fighter, he's one to watch.
