i have been known to play a rough style of basketball ... i like some of the physical exchanges, as long as they are within reason ... it's amazing how many people get upset about getting boxed out or cleared off a rebound
aside from that normal legal activity i'll step on feet, give an elbow to the arms, chest etc
however, there is a line you do not cross ... don't go for the head, knees or other sensitive areas and absolutely never hit someone with a shot when they are vulnerable
few things upset me more than getting undercut and it is one thing that i'd never do to someone ... not even in retaliation for a cheap shot
it's also probably the only time in recent memory where i've been beyond riled up .... i remember in jr. high I went up for a board and this kid crouched and swung his butt into the back of my legs, causing me to fall over his back and sprawl to the ground
he ran back to get into position ... i played out the injury a little and waited for the shot to go up .. he turned to face the basket and I came up and kicked him in the back of the knee
undercutting is probably the most irresponsible thing you can do on the court
