TRUE SHOOTING % and GOOD/BAD%

In the comment zone we were having a discussion about shooting and who is really that good.
These are the numbers I use to evaluate players offensive ability. One is their true shooting %. This accounts for free throws. This is why a player like Vlady comes out very average.
The other number is close to John Hollinger's brick %, but basically it accounts for time on the floor. It tells me in the simpliest form whether or not this player helps his team score. Basically, Chris Weber scores but it takes him so many shots and so many shots considering his minutes on the floor that I believe he hurts his team.
