Jones and Gusto are the example where they’ve set out to stamp out those challenges, with clearly established criteria (high point of contact, leg bent under impact to show sufficient force to endanger an opponent). It’s definitely more harsh than prior seasons but if the standard is “did this endanger the opponent” then bending the standing leg with a high point of contact feels like a reasonable line for actually dangerous. Players will adapt to the standard if they hold the line (and I think they should).
