It makes no sense for GBP to be the culprit in the hold up because Oscar has been very transparent about how eager he is to collaborate with Top Rank and HBO.
It makes no sense for Quillin to be the culprit in the hold up because he stands to make major money and for the first time in pretty much his whole career people are actually giving a solid damn about Peter Quillin.
So that leaves Al Haymon who has seemingly been on a mission to make boxing in 2014 be absolutely shytty for whatever his personal agenda is (I'm assuming it is to keep everything static until he and Schaeffer can move over to running Mayweather Promotions as a competitor to Top Rank and Golden Boy) and if this is the case then it is time for Quillin to be the first of Al's fighters to tell Haymon to kick rocks and actually make a decision for himself.
