Before anyone gets on me about this remember this is just my opinion.
First lets not take away personal choice here. We can cry about this being unfair but this is the sport they choose. This is the weight class THEY choose. Imagine if someone makes up a sport to see who could wrestle a shark...isnt anyone that participates making that choice, regardless of the stupidity in it. My point is they make their choices and no one is forcing them to do this.
As for being drained cause of weight cutting this is again them making the decision to fight at this weight class while weighing a certain amount. Frankie Edgar doesnt play that game and is succesful, he made his choice and it has worked out for him. Others have mastered cutting weight, implying that it can be done correctly and safely if you take the time to learn how to and do it properly. Also when you get to the point where you just can't do it then you take the consequences that come wiht that (losing your payday and the respect of many).
When you hire the best trainers and dieters are and by the best facilities are you not preparing yourself and hoping to have an advantage in the fight. So why is it that trying to do something within the rules to make sure you have a size advantage it is wrong or unfair. His opponent has the same options he does, speaking from the perspective of anyone.
Finally, I will leave with this for those that think the 135er's that are actually fly weights have to fight under sized. In basketball when you are 7feet you have to be either a power forward or a center most likely a center. You can be small and fast but then the big guys bully you. Or you can be big and have a hard time chasing around the smaller bigs. The point is if you choose to compete in a sport you have to adapt to the rules. You arent going to be a 7ft point gaurd but you can control what advantages you want to have at your height. Simple as that.
I against I,
flesh of my flesh,
and mind of my mind,
two of a kind but one won't survive,
my images reflect in the enemies eye,
and his images reflect in mine the same time
