You must know by now I have a major man-crush on the idea of McGee with the Raptors, right? Everyone knows McGee's abilities but there is more than enough articles and rumours out there to confidently say WSH would move him with the right offer. Maybe a young cheap wing they reportedly covet along with another young PF/C both on rookie deals would be enough to do it. I don't know - just throwing it out there.
With regards to Udrih, if he is on the books for 2 more seasons at a bad contract along with Calderon, I'd rather have Calderon as he is a true pass first PG. When the majority of their team is on rookie deals and salary cap is nowhere near a concern, I don't worry about Calderon's contract if I'm Petrie or Maloof brothers. Calderon is an experienced PG who would compliment Evans very well, IMO, and add to his development.
As of now, SAC has $27M in contracts for next season:
