I agree with most that you said except him not being rated high enough for a title shot. Brook was the undefeated IBF welterweight champ, rated #1 by the Ring magazine and rated #10 PFP or there abouts. He was just fighting guy's in title defenses that were too easy to defeat. So he was losing alittle momentum. In his heart he wanted the superfight moment that was elluding him, well he got it.
