Whats worse

Boxings about taking risk so neither are bad if the fighter can handle it.

I think the guy draining himself will only be hurting himself in the long run

There is nothing wrong with either of these things. If a fighter drains himself to make the contracted weight he has done nothing wrong and stayed within today's rules. Blame the bad rules but don't blame the fighters who abide by these rules. As for fighters dragging smaller fighters up two weight classes to fight them that is impossible. The larger fighter can't make the smaller fighter do anything he doesn't want to do.The smaller fighter must want to go up in weight to fight the bigger fighter and agree to the fight or the fight never happens. GGG didn't make Brook come up to 160 to fight him. Brook asked for a shot at GGG and his middleweight title.
