exactly right. Just like Brock had to come down about 25lbs from his beefed up roided WWE days, Carwin will also have to come down a good 15 lbs in order to not gas out like that.
Agree, Carwin needs to drop the weight and not cut before fights.
Plus, IMO I think nerves played a HUGE role in Carwin's cardio/cramping.
Not only did he have nerves of the fight, but also the adrenaline of dropping Brock, then unloading everything he had, only to have Brock take it and stand back up.
That really has to do a number of bad things to you.
