It is okay to play tough and try to hit guys hard in the course of the play - that's fine - but I don't like unnecessary roughness or things that happen after the play.
To be respectful to opponents is to play hard against them.
It's nearly impossible to enforce actual consequences in video games at the moment, but at a table, sitting face-to-face across a tabletop game, or even playing at a LAN party, sportsmanship matters.
I get excited after I dunk. I yell and scream, but it's not yelling and screaming at other players to show them up. It's the way I play. What I do is have fun on the court.
I played it right because that's what you're supposed to do - play it right and with respect.
I am physical, not aggressive. Well, aggressive with the ball, but I don't kick people.
For me, it's fine to be aggressive and play hard. As long as you're not getting personal, it's fine, and you can do whatever you can to upset the opposition.
Can't we all just play nicely and leave the playground the way we found it, clean and safe?
