1) Where have you read that Azubuike is high on their priority list?
2) The best time to offer a contract to Azubuike is 12:01 because the Warriors will have to negotiate with Ellis and Biedrins and may not be able to match right away. Ellis and Biedrins will both be looking for deals near 50 million over 5 years. If their number exceeds 50, the Warriors will have to let Azubuike walk. If you want Azubuike, you get him to ink right off and possibly force the Warriors into a situation where they have to let him go for fear of losing Ellis or Biedrins.
3) I'm starting to wonder if we haven't looked past the Spurs #1 free agent option, Josh Childress. Artest, Smith, Pietrus, Azubuike and Siskauskas dominate our discussions, but why wouldn't the Spurs offer Childress the full MLE just after midnight? If that doesn't work, there are still servicable fall back options available, possibly including Pietrus and Azubuike.
Childress might be their guy.
