Undoubtedly, Dirk Nowitzki is the Mavs' best player of all time. The German superstar played all of his 21 seasons in Dallas and was able to lead the franchise to its first and only NBA title in 2011. A shoe-in for the Hall of Fame, Nowitzki's resume speaks for itself. He's a 14-time All-Star, a four-time All-NBA First Team member, a league MVP, a Finals MVP, and of course an NBA Champion. He is the franchise leader in games played, points scored, and total rebounds to name a few of his accolades. Dirk changed the game and almost single handedly put Dallas on the map as a contender in the Western Conference.
Coming at the second spot is swingman Mark Aguirre. Aguirre was one of the early superstars of Dallas in the 1980s and made it to three All-Star teams in 1984, 1987 and 1988. He averaged more than 20 points per game six times with the Mavs, including a career-high of 29.5 points per game in the 1983-1984 season.
His partner Rolando Blackman also makes the list as part of the top 5 Mavericks of all time. Blackman joined the Mavs alongside Aguirre in 1981 and helped hold the fort for the franchise early on. The shooting guard played 11 seasons in Dallas and averaged just under 20 points per game, making four All-Star teams.
A couple point guards complete the list. Derek Harper, who was also part of the Mavs in the 1980s, is truly one of the best court generals to ever play for Dallas. In 10 and a half seasons with the Mavs, Harper recorded the most assists (5,111) and steals (1,551) in franchise history, records the Georgia native still holds up to this date.
Right beside Harper is Jason Kidd, who was part of the Nowitzki-led team that won the title in 2011. Though Kidd only ranks third in all-time assists and steals, he leads the franchise in assists and steals per game, and he did that in just six seasons. The Hall of Famer was the co-ROTY as the Mavs' second overall pick in 1994 and came full circle as he found his way back to Dallas halfway through the 2007-2008 season, where he eventually cemented his case as one of the best point guards in the league with a shiny NBA ring.
