You can hate on Gilbert Arenas all you want, but it's not debatable that Arenas was an offensive powerhouse when he was healthy and not bringing guns to practice. After some formative years in Golden State, Arenas signed with the Wizards and was on the verge of becoming a star from '04-'07, averaging nearly 28 PPG and six APG while leading Washington to the playoffs. At the tail end of the '07 season, however, he tore his MCL, and never played a full season again. Had he never gotten injured, the Wizards may have had a shot at being a serious title contender and Arenas may have been looked at now as one of the best scoring point guards of his era.
