Evidence is mounting that the Bulls will not match Houston’s offer sheet to Omer Asik.

Perhaps as a fail-safe, Chicago has expressed interest in Darko Milicic, among other lower-salaried big men in free agency.

The Rockets have extended a three-year, $25.1 million offer, which contains a third-year salary of close to $14.9 million.

If the Bulls were to match the offer, they would be subject to a luxury tax for the first time for at least next season and 2014-15.
