There are two main possibilities for Alex Garcia in relation to the NBA:

Alex Garcia (undrafted): This Alex Garcia went undrafted in the 2002 NBA Draft. While he wasn't drafted, he did sign a multi-year contract with the San Antonio Spurs in 2003. Unfortunately, there's no further information readily available about his time on the Spurs, so it's unclear if he ever played in an official NBA game.

Alex Garcia is mistaken for another player: It's possible you might be thinking of a different player with a similar name who did play in the NBA. There are many players who have passed through the league, so without more details about Alex Garcia (like his nationality or specific playing years), it's difficult to say for sure.

Interesting things to consider:

Undrafted players can sometimes find success in the NBA through training camps, summer leagues, or international leagues.

The San Antonio Spurs are known for their strong player development program, so even if Alex Garcia (undrafted) didn't make the final roster, he likely gained valuable experience.
