My only problem with this is that guys can already jump around a lot in weight. That Irish thief-leech burned the sport hard with that. There could be upside in terms of seeing more interesting matchups though. You're right that the talent is easily enough for another class imo.
I will never understand MMA weight classes.
Just look at them, starting on the low end:
125
135
145
155
All that makes sense... 10lb difference between each... but then
170
185
Some reason we jump to 15lb weight differences. THEN
205
235-265
Like... WHAT THE FUCK
We go from even 10lb increments then we jump to 15 lbs... OK, I could MAYBE understand the argument that between 170 and say 180 there isn't a whole ton of difference but then we jump a full 20 and then a full 30 after that stage like... You can't tell me there isn't barely a difference between guys that weigh in at 265 vs HWs that consistently weigh in at 235?
I get part of it was in the early years they couldn't have 900 divisions like boxing seems to have with like MW, super MW, super light MW and all these other weird classes but still...
And before someone goes nuts about my rant about HWs here's the thing... other than say maybe Brock or Mark Hunt when Hunt was at his highest "I just eat burritos to train" days... have we ever really seen super talented HWs that weigh more than like 245?
EDIT:
Or just do what boxing does for HW. Cruiserweight for them ends at 200lbs so let's say we use LHW as an example. LHW is 205lbs.
Anyone over that is a HW. Don't put an upper limit there as you'll never see some 600lber be worth a shit in any sport.
