It's now been 18 years since LeBron James made his debut for the Cleveland Cavaliers. So much has happened from that time and LeBron, who is now with the Los Angeles Lakers, recently looked back at the journey he's taken.

James took to Instagram to send a heartfelt message of appreciation, which also happens to include a bit of a warning for the rest of the NBA (h/t Brad Sullivan of Cavaliers Nation):

LeBron James

The Lakers superstar has done it all in his career. However, as he said in his message above, he's far from done.

LeBron's Lakers have been struggling to start the season, and they are coming off one of the worst defeats in recent memory against a lowly Oklahoma City Thunder squad. LA enters Saturday's matchup against the Cavs with a 2-3 record which at this point, is far from ideal for them.

The good news for LeBron and Co. is that there's still a long way to go this season. What can be considered as a silver lining here is how they've gone through their struggles early in the campaign. Hopefully, the Lakers are able to get this out of the way as they look to reclaim the title.
