A couple years ago, Mark Cuban was lampooned by many for trading a young stud in Devin Harris for broken down Jason Kidd, who had bad knees, couldn't shoot or play defense, and on top of all that, was a malcontent. Sabremetric types almost universally lampooned Cuban for the trade, including John Hollinger, who actually did it to his face at the Sloan Sports Conference
This was further emphasized when in Harris' first full year as a Net, he made the All Star team and averaged, as a 25-year-old, 21.2 points, 6.9 assists and had a 21.6 PER.
Since then, Harris bounced from a terrible Nets team to being Deron's replacement in Utah, and since 2009, his numbers have taken a pretty big downturn - although last year he averaged a career high 8 assists, but only shot 42% from the field.
Jason Kidd, on the other hand, became a key role player for a championship Mavericks team, starting to shoot 3's at a better clip, playing decent defense in the playoffs and averaging between 8 and 9 assists a game. While his rebounding has slipped since his prime, he still remains one of the best rebounding guards in the league (3 years in Dallas with around a 10% rebounding rate, only this past year with a sub 8 rate).
So, obviously, Mavs wouldn't take the trade back now because they won a ring.
However, would the Mavs still have been able to win a ring if Devin Harris was still their point guard?
Keeping in mind: This was the whole trade:
February 19, 2008: Traded by the New Jersey Nets with Malik Allen and Antoine Wright to the Dallas Mavericks for Maurice Ager, DeSagana Diop, Devin Harris, Trenton Hassell, Keith Van Horn, a 2008 1st round draft pick (Ryan Anderson) and a 2010 1st round draft pick (Jordan Crawford).
