He is asking why people are cutting weight if they could naturally be above 205 and just fight the other big dudes. Be the king if HW sucks. But I think you're saying HW isnt as much of a draw, not that it necessarily sucks.
HW boxers used to be the baddest mother fucker on the planet and the most popular, but for whatever reason right talent/entertainment pool is shallow. Mike Tyson was a HUGE draw, so was Evander Holyfield. Tyson Fury, Deontay Wilder, and Anthony Joshua are drawing well now, but not like the 90s.
Mirko, Fedor, Noguiera, Cain, Brock, JDS, Ubereem were all pretty big draws.
Weight class talent pools fluctuate. LHW was the freaking BEST for so long, and now its a wasteland. There arent that many exciting heavyweights right now except Ngannou. Hopefully a few more like him pop up.
