I'm pretty split on open scoring. I think in some cases it would be exciting. In others it would be worse.
I think better, more accountable judges is really the only thing. I don't know how you do that exactly, but it's the most important thing. You can have open scoring with shitty judges. You can have more shitty judges. You can put shitty judges in some sound isolated room instead of having them cage side. You can have shitty MMA specific judges instead of using shitty boxing judges. I think all of these things could potentially help, but you've got to get better judges. Easier said than done, but that's the only answer.
One thing I still don't quite understand is each state having their own judges. If you find some good judges, why can't they just do all of the cards? Open it up to former fighters. Open it up to certain media members. Open it up to refs. This state-by-state thing is just so ridiculous.
