I don’t think we need matside weigh ins.
For one, IMO it seems weight cutting at least in D1 is not as bad as it used to be. Yes, many people still cut weight, but I bet it’s rare that guys are “forced” to by the coaches. But the reason people cut weight is because it is often beneficial, as long as you’re not cutting too much.
So the biggest reason against matside weigh ins for me is that even with matside weigh ins, guys will still cut weight. So IMO it actually makes it more dangerous, as I wouldn’t be surprised to see someone die after wrestling a 2TB match or something. In addition, assuming you need to weigh in with shoes, shoe companies will try to make the lightest shoes possible which could sacrifice safety.
After that, I think the logistics issues are legitimate. Think of how much time this would add to NCAA’s for example. Although I suppose we could get rid of overtime and go to freestyle criteria to offset it…
