Risk vs. Reward... losing to Koborov, while he is good, would put Quillin to the middle of the pack at least. Sure, it would have been a payday then- but what about 4 fights down the line?
If Quillin shockingly lost to Koborov, he would not longer be as marketable.
Saying Haymon had issues is just an easy cop out, and only an idiot would believe that as the overall reason.
Quillin dropped a belt... a major belt... plus money... vs a guy we now know as more dangerous than his record and lack of media hype suggests.
Looking at it now, it had the makings of a Jermaine Taylor/Kelly Pavlik thing to it....
