WHO SHOULD I ADD / DROP !??? PLEASE HELP

[wake n blake]

The league I'm in is HtH with 18 teams. Scoring is judged on Field Goal Percentage (FG%), Free Throw Percentage (FT%), 3-point Shots Made (3PTM), Points Scored (PTS), Total Rebounds (REB), Assists (AST), Steals (ST), Blocked Shots (BLK), Turnovers (TO), Assist/Turnover Ratio (A/T). Currently on my team, I have..

Ricky Rubio
Kobe Bryant
Kevin Durant
Serge Ibaka
Tiago Splitter
Larry Sanders
Derrick Williams
Isaiah Thomas
Devin Harris
Luis Scola

I'm looking to pick up any of the following : Carl Landry, John Henson , Jared Sullinger, Ed Davis, Terrence Ross, Garrett Temple, Earl Clark, Chris Copeland, Jodie Meeks, Will Bynum (Big question mark ???), and MAYBE Steve Novak. So who should I drop, and who should I add ? If you guys have any other suggestions on who to add, that I didn't mention, please feel free to add. I'm in a pretty deep league, so a lot of the players are taken up. Thanks in advance !
