Here is a refresher. All NBA teams have a 15 man roster with only 12 being active for each game. If someone is sent down to the D League, he is still on the 15 man roster. That team cannot pick up another player. The only way you can pick up another player is if you waive someone off of your 15 man roster. Players under contract are not normally waived as you still pay their salary and you don't get to use the salary in a trade. That's why players on the last year of large contracts like Gadzuric (7.2mil), VladRad (6.9mil) are valuable as trade assets to teams wanting to clear salary cap space. With the impending lockout looming, that may change things a bit. However, I would expect that Brandon Wright and Gadzuric and/or Vlad will be traded by the February 24th trade deadline. As for Jeremy, his first year is at least partially guaranteed. I would highly doubt that Lacob would waive him without giving him a legitimate chance to develop. At the least, you send him to the D-League and have him run the point for next years summer league team. If he hasn't shown you he can play at that point, you don't resign him as his contract is not guaranteed for the 2nd year. If he is let go, he would be a free agent and could sign with any interested team.
Statistics don't mean too much if you have a small sample size, and are mainly during garbage time. However, they are numbers and they don't lie and they are not an opinion. What jumps out to me is that defensively (steals, blocks), JLin's numbers are off the charts, while his offensive numbers show how much he has struggled on that side of the ball.
For All Point Guards only:
Steals per 48 Minutes #1 of 73
Blocks per 48 Minutes #1 of 73
