BC is totally at fault. Dangerous play.
I would caution against a mod to the laws without first considering a player leaping an attempted tackle from the side.
There are occasions when hurdling a tackle attempt is an applaudable athletic agility, but it carries exponent risks. Achieve it & win applause, fail & clatter the opponent & lose a PK, YC, or RC depending on how much you endanger/hurt the player.
Accordingly most don't attempt it.
In the clip - it's a PK for me, if knees had struck defender in the chest/neck/head then a YC, & if defender had been semi or fully concussed then its a RC, similar to the high tackle set of barometers.
