According to the Arizona Republic, once the Turkoglu trade is consummated, the Raptors will move Dwayne Jones to the Bobcats in exchange for Boris Diaw. Diaw makes $9M/yr for the next two seasons, the deal would see the Raptors use the TPE acquired in the Bosh S&T.
The Toronto Raptors are set to send forward Hedo Turkoglu to the Phoenix Suns in exchange for guard Leandro Barbosa, according to the Arizona Republic. The Suns would also receive Josh Childress, who would be acquired in a sign-and-trade deal with the Atlanta Hawks, the Republic reports.
This I can explain. His low usage rate when he is on the floor minimize his impact on team stats, such as team O/D rating and even plus minus (since that stat also accounts for the other members of the rotation. However, when he is being used, his individual stats, or the stats that are only dependant on his contributions, he looks pretty good, pretty great even.
Basically, like what everyone else has been saying, it comes down to usage rate. Involve him enough in the offense and there's no reason why his individual efficiency won't be reflected in the team stats.
Now here's where you might say "but the raptors lose more when he shoots more than average, so the usage rate argument doesn't hold up". That's a fair point, but I would argue that Jonas often gets those extra field goals when A) the guards are putting up a ton of bricks and Jonas is cleaning the glass, or B) he's a last resort after its clear that the other scoring options aren't working. In both scenarios, the team as a whole is playing below average, so it makes sense that they would win a lower percentage of games.
