Incorrect Drafting Years - NBA 2K14 EuroLeague Teams

I was looking through the PS3's roster for the EuroLeague teams and noticed that there were some players (all of whom were drafted to NBA) that had their draft year on their player cards incorrect and ONLY their draft year. I remember 3 off the top of my head but there was surely more. Weirdly enough, only the year is messed up, the draft round, pick, and team is all accurate.

These 3 players are:
David Andersen: Listed draft year of 1998, actually 2002.
Bojan Bogdanovic: Listed draft year of 2006, actually 2011.
Semih Erden: Listed draft year of 2003, actually 2010.

No clue if this is a bug or what.

Quite likely a data entry error, yeah.

Yeah, it appears that the years here correspond (relatively) to when the players played with their first pro club, not the NBA.

Correct me if I'm wrong because I just took this for the players' wikipedia articles.

David Andersen was on teams as early as 1995 but he made his NBL debut in 1998, same year as listed on 2k14.

Semih Erden made his in 2003.

Bojan Bodganovic started playing on Pro Teams in '04 so not quite the listed date but he was signed to a EuroLeague team in 2005. Never played on their main team though.

I'd say that's a good guess, it's definitely plausible. Just an oversight while cross-checking their info, I suppose.
