I don't know if Cormier can make 205, without dying in the process, tbh.
Strikeforce heavyweight Daniel Cormier, who just snuck into the SF Heavyweight Grand Prix tournament as an alternate replacing Alistair Overeem, had to miss his shot at Olympic gold in 2010 when his kidneys failed in Beijing. Cormier was cutting weight to compete at 211lbs.
Now he's a permanently undersized heavyweight who doesn't dare try to make 205lbs because he doesn't dare push his kidneys again.
Cormier is no doubt familiar with the symptoms of Acute Renal Failure (ARF) like dry mouth, lack of urine, headache, lower back pain, nausea, and drowsiness. ARF can be treated with fluids and a quick rehydration, but it can also become Chronic Kidney Disease (CKD) if the fighter's kidneys give out from the strain.
It's not just the kidneys that don't do well when the body is drained of fluids. Dehydrated brains are an even bigger threat to fighter health. Boxing fans old enough to remember Duk Koo Kim know why same day weigh ins are a thing of the past. Kim took a 14 round beating from Ray "Boom Boom" Mancini the same day he made a brutal cut down to 135lbs.
Without sufficient time to rehydrate before the fight, Kim's dried up brain slammed against his skull every time Mancini's gloves made contact and after 14 rounds it was too much. Kim died 4 days after the bout.
MMA fighters need to be aware of the dangers of weight cutting when they sign those contracts and hit those scales. As long as fighters think they can get an advantage by fighting in a smaller weight class and coming in heavier than their opponent these risks will be with the sport.
But it would be interesting to see him against either guy.
However i see him at HW.
