It has been more than 12 years since Steve Nash left the Dallas Mavericks, but Mark Cuban still regrets his decision of not re-signing him when he had the chance to.

When asked what was one of his biggest mistakes as a team owner, Cuban quickly revealed that it was all about the Canadian point guard.

Nash was a decent starting point guard for the Mavs before he decided to bring his talents once again to the Phoenix Suns where he started his professional career. He then turned into one of the best players ever and won the MVP award two times in 2005 and 2006.

One has to wonder, including Cuban, what could have been for his team if he extended an offer to Nash that time and if he went on and continued to play for the Mavericks. He and Dirk Nowitzki would have created one of the best duos in the league and could have competed for a lot of championships that time.

Dallas moved on from Nash and competed for the title in 2006, and after multiple playoff appearances after that, eventually won a championship in 2011. Nash, on the other hand, never won a championship but was a perennial All-Star and one of the top players in assists year in and year out.

Nash officially announced his retirement last year after his injury-plagued stint with the Los Angeles Lakers where he only saw action in a combined 65 games in his final two playing seasons.
