TBH I don't believe this at all (the info, not that you were told).
Why would Jerome remove his clauses, what is his motivation to do so? He had been repeatedly asked about them and always deflected and by saying he is committed and they are nothing to worry about. For him to then all of a sudden just remove the clauses doesn't make sense.
Additionally, we repeatedly see contract negotiations for high end players take a couple months (usually longer when Moses is involved). It was only really early November that we heard of any negotiations between Richo and Bula. I'd doubt that he was suddenly ready to sign so quickly into negotiations, particularly when he couldn't have other suitors until November (in accordance to the very poorly regulated anti-tampering rules). Finally there were journos at the time guessing that Bula was not going to re-sign whilst Richo was still here. It all adds up to he probably wasn't all set to sign prior to HBG.
I'm not saying this as a defence of HBG at all. They seem to be incompetent. But I believe their incompetence and Bula delays are not necessarily directly relate (though certainly doesn't help).
