5. Antawn Jamison
One player who won the Sixth Man of the Year award was Antawn Jamison. The former Mav was the leading recipient during the 2003-04 season.
Jamison came to Dallas as part of a nine-player trade that sent Nick Van Exel and four other players to the Mavs. The trade worked out for both sides as Jamison and the Mavs finished as the fifth seed in the Western Conference, only to lose to the Sacramento Kings in the first round.
In his first and only season with the team, he averaged 14.8 points per game and pulled in 6.3 rebounds. This was a drop compared to his past averages, as he was not accustomed to coming off the bench.
Jamison also was the team's third-leading scorer that season. He shot 53.5 percent from the court and knocked down 40 percent of his attempted 3-pointers.
However, Jamison's production would not be enough, as Dallas would trade him later for another sixth man in Jerry Stackhouse. His frustration with coming off the bench and lack of defensive effort were some of the reasons the Mavs traded him.
In his one season with the team, Jamison was a offensive machine who could provide buckets off the bench. Too bad his time in Dallas was cut short.
