Mark Jackson was among a group of current and former NBA players in Manhattan on Tuesday for the premiere of NYC Point Gods, a documentary from Kevin Durant about the history and cultural impact of top lead guards from New York City in the 1980s and 1990s. During an appearance on the red carpet Tuesday, Jackson took a few questions from reporters. One question: Does he ever think about what the Knicks could have done if they didn’t trade him? “Well I do believe that we win a championship,” said Jackson, who was traded to the Clippers in a three-team deal that sent Doc Rivers and Charles Smith to New York in 1993. “We had a great team, we had a process moving along, we advanced. We had the ultimate champs on the ropes. So I believe we win a championship if that team stays together. But I’m sure if you ask the opposition, they believe they win anyway.”
