Jordan hears the criticism that he’s too slow for the modern NBA. Too heavy-footed, too old. His best days, they say, are far behind him. When he signed with the Nets, he was branded as the expensive add-in — a necessary price to get two superstars.

Jordan’s experience, coupled with his defensive prowess and potential to guide Allen, made him attractive to the team. And being close with the Nets’ supermax duo didn’t hurt.
