New rules on contact / hand-checking

[Kansas Ref]

Well, this is a fine thread about "hand-checking". In pre-game me and partner talk about how to recognize it, which is usually occuring when in Trail position and we're observing the guards bring ball up under close defensive pressure or on the wing area when SF is jab-stepping. Ball-handler is making all manner of spin moves, between leg dribbles, and crossover dribbles to evade defender. We notice that when defender was shuffling defensive footwork they would extend a hand to put on dribbler's hip then quickly take it off. Then, during the half-time, me and partner would lament that we missed those calls, and also talke about/self-evaluate and ask selves "did that teeny bit of contact impede dribbler?", then at second half, we'd try to make the adjustment calls and try to strike a balance. I'd say we then had 2 or 3 more such calls.
