In theory it doesn't even have to be the ballhandler who can run into him and draw a technical, right? They should see if Kevon Darton wants to play a little basketball, and when a coach keeps doing that when they're in the press to take away space, sub him in and tell him to just start in the front court and race back into the back court and run straight into the coach at full speed - let the ball carrier dribble towards that coach a bit, make sure he's not looking at the 271 pound ball of fury running at him from behind.
Once the opposing coach regains consciousness, he can be informed that he got a technical.
