Shakur is what Bob Arum did promise Loma if he win so we might see this matchup at the end of this year if Loma won't consider retiring from boxing as he floats that idea because he said that he is now old for boxing. Against the young Shakur, Loma will be having a hard time as the former is a counter puncher and also technical but lack the experience, the biggest disadvantage of Shakur.
At this stage of his career, i don't think that Loma could unify all the four belts because he is running out of time.
Yes, will be hard for time to unify not only because of his age but boxing politics as well. And his boss might have a hard time negotiating against Shakur as he is no longer with Top Rank or left Bob Arum already. And then against Tank Davis, we might want to be the A-side against Loma.
At least Loma finally gets a 135 lbs, hard to see him crying when he lost against Haney.
But this time, he won and can finally have that tears of joy.
