1. You can take 3 full steps before shooting and it's not a travel. But if you drag your pivot foot a couple of inches it's a travel.
2. There is almost no such thing as a carry anymore. You can almost hold the ball in your hand for a full second mid-dribble and then continue without a call. There would be carries called on nearly play if they called it like they did when I was playing in HS and college.
3. How tie ups or jump balls are officiated is crazy too. If the ball is loose on the floor and one player dives on the floor to secure it, it seems that opposing players can jump on or dive into the player with abandon, hacking and scratching while reaching for the ball and if he touches the ball a jump is called. You almost never see a foul called in one of these scrums anymore.
4. And when was the last time you saw a 3-second violation called? Players hang out in the key for pretty much as long as they want with no concern for ever being called for it.
5. It used to be "the hand is part of the ball." Given the way games are officiated today, that needs to be changed to "any part of the arm is part of the ball." I see players getting hacked and raked on the arms all the time (happens to BYU regularly) and it is rarely called anymore unless you're a star, name player.
The question is, is the game better or worse with all of these adjustments? Basketball used to be called a non-contact sport. It is anything but that these days. If you aren't pushing and shoving and hacking these days, you most like aren't going to be winning. "Physical Teams" are celebrated. They seem to be the teams that can foul the most without being called for fouls. It's an entirely different game than when I grew up.
