I'm going to call one on myself.

So, traveling and palming are not lost in history and memory.

Because, apparently, refs aren't ever going to call it again.  Hint:  it is impossible to switch directions with the ball in one's hand without stopping the ball from going the direction that it was headed in before the switch of directions.  That stopping of the ball in one's hand is a stop (really).  A re-start in another direction is an illegal re-start identifed as 'traveling' or 'palming.'  If they'll let you get away with that move or the both-feet-jump start to your drive (also traveling), then there ain't no way that I can defense you.

I wouldn't quite go that far. Generally, guys still aren't allowed to take four steps while going up for a dunk.

One other rule that seems to be relaxed to me is continuation. I've seen quite a few baskets counted where a guy gets fouled, takes another dribble through the contact and then shoots cleanly to get an and-one.

That seems especially true in the younger AAU levels.  Kids are allowed to plow through kids to get the ball.  It's almost like the soccer slide tackle rule. As long as you touch the ball first it doesn't matter what happens after that.   I'm all for teaching good aggressive defense, and there is some benefit to the ballhandler learning how to protect the ball, but when a kid gets knocked down hard to the ground over and over it borders on ridiculous.

Thanks to you both. I agree it's probably more common at the AAU level. It drives me crazy because many times, you get continuous "jump ball" calls through the course of the game, and clearly you would need to foul in order to gain possession.

Yes, the illegal contact is what I'm talking about. However, I thought there was a foul, at one time, called "reaching in"? Whether or not that's true, the point is, in order for the opponent to get hands on the basketball, they would almost certainly have to make contact.

Here's the scenario (picture youth ball): One kid scrambles to gain possession of a loose ball, which he does. He stands with ball tucked into his belly and waiting for traffic to clear. Opposing player "reaches in" to grab ball, but it would be nearly impossible to grab the ball without making contact. Ref blows "jump ball."
