The Hollinger stat "True shooting %" is basically an improved points per shot-- it is a measure of how efficient a player is with his shots.  The formula is:

True Shooting Percentage = (Total points x 50)/[100*(FGA + (FTA x 0.44))]

Here are the Blazers TSPs:

Joel- .718 (3rd in the league- this dude knows what he can and can't do).

Rudy- .660 (12th in the league- if someone has to shoot ridiculous shot clock beating fallaways, it should be Rudy... and not Outlaw)

Batum- .571 (75th in the league, 16th among SFs)

Blake- .570  (76th, 10th among PGs)

Roy- .532 (127th, 29th among SGs... this is unacceptable from Roy.  He has to be more efficient with his shots.  Edit: Roy is right around his career TSP.  I think this does provide some evidence that we run too many clearouts for Roy.  He's a terrific player, but shooting efficiency is one area where he could improve.)

Outlaw- .529 (136th, 26th among SFs.  Outlaw is not going to keep hitting 3s at his current rate.  Edit: I'm not saying he should stop shooting 3s, just that I feel his TSP will drop if his shot selection remains the same. If he doesn't start taking smarter shots, he's really going to hurt the team)

Oden- .521 (I wouldn't worry about this- in his last two games his TSP is a healthy .699- we need more data on Greg).

Aldridge- .480 (225th, 52nd among PFs.  This is bad, really bad. For reference, Bosh is at .615, Pau is at .574, Zbo is at .521... even Kevin Durant is at .493).  We can't afford for our #2 scoring option to be so inefficient.  If Aldridge takes better shots, we can be the top offense in the league.

Sergio- .466 (Yikes, at least he doesn't shoot very often).

Channing- .404.  (Double Yikes- shooting is Channing's strength.  Last year his TSP was .529-- still not great, but not bad for a role player.  I expect this number to climb).

In summary, Rudy is awesome, Joel knows his role, there's room for improvement from Roy, and Aldridge and Outlaw are really hurting the team with their brickfests.
