Dallas Mavericks all-time draft bust starting shooting guard: Maurice Ager
Ager is the only late first-round pick on this list as he was taken 28th overall by the Mavericks in 2006, just after the team reached the NBA Finals for the first time. The 6’5 went in the first round because of his athletic and scoring abilities. He was viewed as a high upside prospect, but things never worked out.
Ager never nailed down a consistent role before being traded to the Nets at the 2008 deadline in an eight-player deal that landed Jason Kidd back in Dallas. The trade laid the foundation for the Mavs championship in 2011, but Ager was not a key piece of the deal.
The 2006 first-round pick played just four seasons in the NBA where he averaged 2.1 points and 0.6 rebounds in 6.2 minutes per game over just 82 contests. Ager could never find consistent playing time, and those raw tools that got him drafted in the first round never fully developed.
Paul Millsap, P.J. Tucker, and Steve Novak were all drafted in the second round in 2006. It was far from the deepest draft, but selecting any of those three players would have given Dallas another rotation piece as they looked to build a perennial title contender around Dirk Nowitzki.
