Here's the appropriate question. How many of those "hoppings, palmings, etc." were examples of the coaches not knowing the details of the rule. Example, how many times do you see a legitimate jump stop on the perimeter by a 3-point shooter? I see it quite a bit. Even had that followed (or preceded) by an actual travel I called on the other end. Coach complains, but he's wrong.
How many times does a coach thing displacement is another word for "over the back?"
How many times does a coach want 3 seconds called when it's not appropriate (by rule, not interp)?

Finally, how many of these might simply be missed calls (as in, with so much going on, officials didn't catch something) rather than blatant and purposeful disregard for various rules?

Now, if you call 3 seconds when the post player has a toe on the free throw line....
