Looked very intentional to me.
GSP officially back. He will face bisping.
Time to ban weight cutting?
I think it's past time to ban weight cutting.
Time to move from weight classes to height classes?
However, I do believe that reasonable standards can be imposed. Evaluate fighters in camp and see how much they actually weigh, make averages and define a safe weight for them to get down to.
That would be the other option ... regular weigh-ins and have guys fight at their "training weight". But it means a lot more infrastructure and cost to have this all set up.
I think they made add more weight classes to get more belts for marketing purposes, but in terms of rules around weight cutting, sadly I think someone is going to have to die or come close for those to change.
I think you are correct in assessing the disinterest that UFC has in looking out for fighters' health.
But since we're solving the world's problems, let me suggest this. A fighter picks the weight at which he wants to fight, and enters that weight class. At the fight ... in between entering the ring and the start of the fight ... both fighters weigh in. For every x number of pounds the fighter is over the weight class, he loses a point. Three strikes ... er, points ... and you're out ... disqualified and the other guy wins. Have a back-up fighter waiting "just in case" if you want, but, there you go.
Or how about this ... if a fighter is more than, say, 5 pounds over, if he KO's his opponent (or TKO stoppage) then the opponent wins. Make it a real dis-incentive for guys to come in overweight. (Obviously, the fighters have to have a realistic connection with their chosen fighting weight ... we can't have heavyweights pretending to be welterweights and dominate ... but if a guy has a bit of pudge, then penalise him and let him fight.)
