Donnie Nelson wishes Jason Terry luck

Jason Terry has not formally agreed to the three-year, more than $15-million deal the Boston Celtics have offered, but it's probably only a matter of time before he does.

Terry planned to give the Dallas Mavericks, the team he's played for the past eight seasons and won a championship with in 2011, a chance to match. But those hopes have seemed to evaporate.

Mavs president of basketball operations Donnie Nelson, moments after Deron Williams broke the news that he will re-sign with the Brooklyn Nets, all but bid Terry farewell.

"What Jet did for this city and franchise will never be forgotten," Nelson said. "He's one of the greatest clutch performers in the history of our game and even a better person. We wish him nothing but the very best."
