You are both right, believe it or not.
Just looked up his stats, he was not very good early in his career but finished his 5th season at UNO very good from 3 point range.
2003-2004 .311 from 3 point land, while scoring 13.1 points per game
2004-2005 .260 from 3 point land, while scoring 22.6 points per game
2005-2006 .300 from 3 point land (only played 4 games), while scoring 19.0 points per game
2006-2007 .333 from 3 point land, while scoring 25.0 points per game
2007-2008 .405 from 3 point land, while scoring 23.2 points per game
So you are right, he was not very good early, average at best, as a senior he had an incredible 3 point %, not only that but in his career overseas he is an average .329 shooter, including 2010 and 2011 when he shot .438 amd .526 respectively from 3 point land.
