One of the most frustrating players that I have every cheered for, Crawford was an enigmatic presence during his four and a half seasons with the team.
For one thing, he almost never played defense. His defense was downright deplorable and the opposing guard would almost routinely have a big game against the Knicks. Not it was not a coincidence.
Also, for a professed combo-guard, Crawford was essentially an undersized shooting guard (like the other four hundred that the Knicks have had in recent years). He could bring the ball up the court well, but didn't accumulate many assists and would jack the ball up pretty quickly before waiting for the offense to get set.
At the same time, Crawford was an explosive scorer who could go off on any given night (see his 52-point game against the Heat for reference) and score in a variety of ways and got better as the years went on. His three point shot became more consistent, he stopped settling for jumpers and drove to the basket effectively, and if his shot wasn't falling, he knew when to shot shooting and start distributing (such as the 2007-08 season where his field goal percentage and assists both went up).
Also, Crawford was a team leader and good community guy off the court. In an era filled with malcontents, Crawford was a genuinely good guy and somebody that Knick fans could actually be proud to have on their team.
What else endeared him to Knick fans was his clutch play. So many times, Crawford would hit a big shot in the last minute or at the last second to win the game. His game-winning shots were the one thing keeping Knick games watchable over the last few seasons and while his inconsistency during the game would usually cause the Knicks to blow a big lead leading to a need for him to hit the big shot, it's all part of the enigmatic player known as Jamal Crawford.
