You don't know anything, because there's nothing to know. He's a 25-year-old nobody from the Spanish league, who has never averaged 10 ppg or 5 rpg in his 5-year pro career.
He averaged 14.9 ppg and 6.4 rpg in 2010-2011 for Murcia.
Guys who might play 20mpg in Europe may be NBA-ready, so I wouldn't place too much emphasis on per game stats in evaluating players from overseas.
No, he averaged 6 pts and 4 rebounds in 15 ppg that year. Don't know where you're getting your stats from.
edit: Oh, whoops, that's for 09-10. DX doesn't have stats for 10-11, interesting.
