Why on earth would anyone want Bargnani? He is not only one of the worst players in the league right now, he is a HISTORICALLY bad player. He is a horrible rebounder, awful at team defense (and only adequate at one-on-one D), and not an efficient scorer.
Look at his advanced metrics. The AVERAGE NBA player has a WP48 score of 1.00. Bargnani's is NEGATIVE 17.8 ; this means his poor performances cost his team almost 18 wins over the course of an 82 game season. Since 1978, only 6 players in the NBA have had worse seasons than Bargnani. Jason Collins, Kevin Duckworth, Maurice Taylor, James Edwards, Jeff Turner, and Cliff Robinson. Bargnani is cancer to a team. Hell, Alonzo Gee scored more efficiently AND grabbed more rebounds than Bargnani this past season, and he's a shooting guard!
Here, read some of the articles on Wages of Wins about him:
linkNot only should we never trade for a player as hideously inefficient and damaging to a team as Bargnani is, but he has no business even being in the NBA to begin with. Just awful. I don't understand why anyone can watch him and think he's even halfway decent.
