I think ANderson would be a backup plan in case JT gets an offer we don't want to match. So, in this scenario, it's right to have a plan B. I wouldn't overpay for him, because he still has some question marks. Can he be effective without Dwight? Last season, when Howard went down, Anderson started to struggle and play worse. The good thing is that we have big Cuz in the middle, and Ryan could open up space for him and hit the 3 when they double Cousins.
But the question is, can he play the 3? The simple answer is "no". I checked some Orlando Magic boards, and they where laughing when they read we would like to play him at 3. They say he's not athletic enough to guard 3, and he would be killed on D. I agree with that, I don't believe he is a 3, but I also think that we could find a way to play him, Robinson and Cousins together. Maybe Petrie think that Robinson is quick enough to guard SF's. Personally, I'd rather have T-Rob on Lebron than Evans or Salmons. If this is the case, T-Rob could be a 3 on defense, and a 4 on offense, with Ryan Anderson being a 4 on defense and a 3 a la Peja on offense. That's a big lineup, no smallball there. Will it work? I don't know. Is he a perfect fit? No, but he fills a need. We need outside shooting. We would still have a lack of shot blocking, but if Hassan will start to see good minutes, maybe we already have our shot blocker for 15 minutes per night. I also believe Anderson is a good defender, at least agains 4s, so we might even improve on D with him and T-Rob out there, along with Cousins, Evans and Thomas.
If we get him, I highly doubt JT will be back. But right now we don't know what JT is doing, if he really wants to come back or if he's waiting for some offers. Maybe he doesn't feel like coming back after the Kings drafted Robinson. Who knows. At least I'm glad to see some sort of activity by the Kings in this FA market.
