Throughout NBA history there have been more than 4,400 players, and the average career length is around 4.5 years. This is not surprising considering that basketball is a dynamic, fast-paced, very physical sport, so it is not common to see players over the age of 35 in the league, let alone 40.

However, there are always exceptions, and there have been a handful of players who have stayed in the NBA for a long time, competing at the highest level for 15 or even 20 seasons, which is absolutely admirable. With that said, let's now take a look at the NBA players who have played in the league the longest.

The Cleveland Cavaliers selected Jamal Crawford in the first round of the 2000 NBA Draft, but on the same day of the draft he was traded to the Chicago Bulls, where he played his first four seasons. The guard then played four seasons with the New York Knicks, later being sent to the Golden State Warriors for one season before being traded again, this time to the Atlanta Hawks.

Crawford played one season with the Portland Trail Blazers and then wore a Los Angeles Clippers uniform for five seasons. The three-time NBA Sixth Man played his final three seasons with the Minnesota Timberwolves, Phoenix Suns and Brooklyn Nets.
