Chicago Bulls rookie power forward Bobby Portis is one of the most intense players on Fred Holberg's roster and he recently sat down with CSN Chicago to discuss how he gets himself mentally prepared for games.

As you can see from the video clip above, the former Arkansas Razorbacks standout stated that he pictures opposing players hitting his mother in order to build up the type of aggression that Bulls fans have grown accustomed to seeing out of Portis each and every time he takes the floor.

Every player comes up with interesting ways to motivate themselves and, while the rookie's method is a little different than what we normally see, it clearly works for him.
