4 years, 38 million. OK, I get why he opted out of 1 year 15 million now. No way he was going to get a 3 year, 23 million deal next summer (or whenever the lockout ended).
What I don't get is why the heck the Spurs do this? Sure, they will save some tax money this year, but do they really want him tying up 10 million in cap space for 3 more season after this? Maybe non-guarantees or team options will explain it - can't wait to see those.
