If there's any changes to charges, I wish it would be that the defender doesn't need to fall down to to get one called.
Right now everybody takes charges on their heels. The Ja Morant play, I don't think he could ever knock AD off his feet if AD was trying to stay up. With the Giannis play, even as strong as he, shouldn't be able to knock Kevin Love over like that while also sending Love back 3 feet. I think the defender not falling down might lead to fewer injuries for the offensive player (because it's creates less of an undercut).
1) Train the refs to be able to call a charge without having to see a defender fall over.
2) Disincentivize the defenders to not fall over somehow. +1 point for the offense for every defenders butt that hits the floor on a possession where they score. Buckets scored on plays where the defender falls over worth double. Blocking fouls count as 2 fouls on the defender if their butt hits the floor, etc.
Obviously these are fanciful ideas, but come up with something, I hate that defenders are encouraged/expected to fall over with contact, but I understand why because it's the only way to get a call. Still ridiculous though, like teaching your guard dog to play dead when strangers approach. What it would really take to knock some of these players off their feet would look more like a
football circle drill if players were actually trying to stay up.
