Agree with the 'no-brainer' and I understand the skepticism, but West might be their only movable significant contract:
Peja Stojakovic $13,392,000 (ETO)$14,256,000
James Posey $6,031,800 $6,478,600 $6,925,400
Morris Peterson $5,800,000 $6,200,000
Darius Songaila $4,526,000 (ETO)$4,818,000
I can't see them moving Okafor less than a year after acquiring him, so West makes sense; I don't see a team touching any of those other contracts unless some kind of bidding war ensues for West. And as we saw this summer, there aren't too many teams willing enough or in the right financial position to make such a move; the Spurs' all-in approach and desperation to capitalize in the here and now makes them one of the few.
West for expirings and a promotion for Hairston?
'Tis the season...
