Looks like the Spurs just got better. Finley has been rumored to be the amnesty domino that has held things up and will likely start things off. When I have a minute I'll expound on these, but some things to consider.
Spurs now have an excess of bodies that could be available at the right price. Brent Barry and Rasho come to mind. But don't forget Devin Brown.
Effect on C's - I'd still be in favor of a Blount for Rasho swap, and Danny has tried to get Barry in the past. But beyond that, it just means that the Patriots of the NBA are still really good.
Earl Watson seems like the last man standing in the "big-name" free agent department. He could land in Denver, but I'm not sure how they'd work that all out. He'd be behind Andre Miller and fighting Boykins for the backup spot.
Heat need to move on and still have that MLE to use. They could just resign Damon Jones. Not sure why they don't go after Watson.
Effect on C's - Little to none.
Spreewell still looking to feed his family.
Effect on C's - Hopefully none at all.
Yao resigning with the Rockets effectively makes the Lakers 3 year plan look a bit silly. I'd be drop dead shocked if they were able to get either Amare or Dirk. Cap room is so overrated.
Effect on C's - Beat LA! Beat LA! Beat LA!
