Think it's more to do with having to be within a certain percentage of the weight by a certain time more than the early weigh-ins themselves. All fighters I've talked to absolutely love the early weigh-ins, even Scoggins, and they stopped him from attempting to fight, which makes me wonder how Borg made it...
These problems will continue until we achieve same day weigh-ins. Sad that the most dangerous part of the sport is the weigh-in.
