While Marcus Fizer has been invited to work out with Karl Malone during the offseason, writes Daily Southtown's Paul Ladweski, he issued a sound warning to the Chicago Bulls that it would be a mistake to trade him.  "It would be a mistake to trade me," said Fizer, who was selected to the All-Rookie Second Team last week. "There's no question that I'm a better player now than at the start of the season. I've taken a different approach to the game. I'm more disciplined than I was before. I don't rush things as much as I did. Now I'm a lot more comfortable on the court."
