Jordan's change of heart left Dallas with unspent money under the salary cap. Last week, guard Wesley Matthews also renegotiated his contract from $57 million to $70 million over four years.
In total, the Mavericks will pay Barea and Matthews $23.3 million more than they had planned. Jordan's contract would have been valued at $80 million over four years.
The 2014-15 season marked Barea's return to Dallas after a three-season stint with the Minnesota Timberwolves. Barea has played six seasons of his nine-year career with the Mavericks.
Last season, Barea played 77 games and averaged 7.5 points, 3.4 assists and 1.7 rebounds per game.
