First of all New Jersey didn't have Travis Outlaw when the FA period started.
Second, if RJ is as good as he's billed here, he should have been a significant upgrade over Gallinari or Chandler in NY. Same could be argued for Sacramento.
Third, we still don't know what the Spurs offered or even what they were willing to match for RJ. Were they interested in matching a 5 year guaranteed deal? Over $10m/per deal? RJ made clear we was looking for a long term deal, but the Spurs never really stated what they would offer, simply that they would like him back.
Fourth, add the Blazers who handed out a $33m/5 year deal for Wesley Matthews. The Suns after moving Amare had a huge trade exception that they decided to spend on Hedo + pieces. Same for Toronto after the Bosh deal.
So, you know, the fact that two days ago we were scrapping the bottom of the barrel for a starting SF, and we still are to see if we can pick up a backup pretty much tells you that the market was very active for those guys.
Which makes the lack of demand for RJ even more glaring.
