Dont let Mbaye poor/pathetic performance take away from Rees' win. nobody knew how good Rees is and in fact we still dont know, but Mabye definately was trying for the KO late on. I dont see any fix.
What I saw was a guy who clearly wasnt motivated for the fight, who had been out fo the ring for a hell of a long time and didnt expect Rees to be as competitive as he was. Also he wasnt a very good champion to begin with. Yes ofcourse the other champion would probably KO Rees, but thats not the point, the point is nobody thought he could beat Mbaye for the WBA title and he did! FAIR AND SQUARE!
