ESPN.com suggested hang-ups to Boozer-to-the-Bulls were twofold.

One, according to an unnamed source and as written on the Web site: "Concerned about the quality of its backcourt rotation if it has to surrender (guard Kirk) Hinrich (to Portland) with Thomas after losing Ben Gordon in free agency, Chicago would insist that the Blazers surrender young guard Jerryd Bayless, which Portland is reluctant to do."

The other: "If it can't get Bayless, Chicago might still be willing to substitute Tim Thomas for Tyrus Thomas in the deal, but sources say Utah would likely balk if Tyrus Thomas is not included."

Golden State and Miami are believed to be other possible destinations for Boozer, but Detroit — once a supposed suitor — evidently is not.

According to ESPN.com, "sources with knowledge of Detroit's thinking insisted again Friday that the Pistons will not join the trade bidding ... because they think Tayshaun Prince and newly signed Charlie Villanueva will complement each other better than Boozer and Villanueva would."
