Phil Jackson said his biggest mistake since taking over the New York Knicks was not taking Jae Crowder in the Tyson Chandler trade with the Dallas Mavericks.

Crowder emerged as one of the NBA's best defensive players since his trade to the Boston Celtics.

"One of the first deals I engineered when I came back to New York was to trade Tyson Chandler and Raymond Felton to Dallas for Shane Larkin, Jose Calderon, Wayne Ellington, Samuel Dalembert, plus a second-round pick that the Mavs owed to the Celtics," said Jackson. "In talking with (Dallas), I was given the option of taking that pick or else taking Jae Crowder. I liked Crowder but I thought he wouldn’t get much of a chance to play behind Carmelo, so I took the pick which turned out to be Cleanthony Early. While Cleanthony has missed lots of time in the past two seasons with us, he still has the potential to be a valuable player. Even so, I should have taken Crowder.

“Anyway, for all of us, making mistakes are part of the learning process."

The Dallas Mavericks offered Dirk Nowitzki a two-year, $50 million deal, which was more than he asked for in free agency.

Nowitzki was on a discounted deal previously.

“Dirk wasn’t even in the country and people couldn’t even reach him when free agency started,” Mark Cuban said. “I basically told him, look, you tell me the price and it actually started lower. His agent said ‘how about this much’ and we said ‘we’ll have a little more money, we’ll give you more’ and as the numbers started getting bigger and bigger, it was like ‘what about this number?’ ‘We’ll give you more.’ Finally, it was like ‘this is what we got left, take it!’ We wanted to make it a two-year deal with a team option so that people wouldn’t speculate that he was going to retire because Dirk is the type of guy, he’s just a good guy. He would hate going city to city to city and everyone asking him if he was going to retire because he has no intention of retiring after this year and, with the team option that we have, he gave us the flexibility that said ‘if we find somebody that we can send the money to that he likes, we all like, then let’s do it and if not, let’s give the money to Dirk again which I’m fine with too.”
