Yeah I don't get the "holding division hostage" stuff. It gets thrown around so much these days as well.
Bisping defended the title within 4 months of winning it. He's willing to defend it again in December in a "Money fight" whilst the other contenders fight each other. A fight with Rockhold/Weidman/Jacara/Romero was never getting made for 206 were never fighting at 206 considering 2 are fighting at 205 and the others are fighting 2 weeks before the event. Him fighting at 206 and winning would never of slowed down a potential fight against the above 4 if it was to happen at the time it was scheduled to. I.e. 209/210 or something similar. People are slating him without the fight even being made. Maybe I'm bias myself but I can see his logic to be honest, he probably knows deep down he'll lose the title if he fights a top level fighter so might as well cash in against people he has a good chance against (Diaz) and make good money there, fight later on against a contender at a scheduled event and probably lose. It's not his fault them 4 fighters were booked close to 206. Equally people seemed excited about the clashes and now 1 is off, again due to no ones fault but AKAs training regime I'd guess, he's cherry picking and ducking. I've not got the interview to hand but he even said when asked he was basically taking them fights to make some good money and would then fight a realistic fighter once it's all sorted out. He may be a ducker but at least give him the opportunity.
For comparison Weidman defended his title roughly ever 7ish months, Rockhold defended it after 6 months and Anderson averaged about once every 6 months (although early on there was phases where he fought every 3-4 months.)
It's surely to early to tell if Bisping is holding a division hostage. He could potentially fight 3 times in 9 months. Equally it got announced 24 hours ago that Rockhold was injured and people slate Bisping already, just see what happens first.
