The Detroit Pistons traded forward-center Darko Milicic and point guard Carlos Arroyo to the Orlando Magic for Kelvin Cato and a 2007 first-round pick, ESPN.com learned Wednesday.

The little-used Milicic appeared in 25 games for the Pistons this season, averaging 1.5 points per game in 5.6 minutes. Arroyo, a reserve guard, averaged 3.2 points and 3.1 assists in 50 games for Detroit.

Cato averaged 13 minutes in 23 with the Magic, averaging 3.8 points and 2.7 rebounds.

Milicic didn't play much more for Flip Saunders than he did for Larry Brown, unleashing a new wave of second-guesses on Detroit's decision to draft the Serbian 7-footer over Carmelo Anthony, Chris Bosh and Dwyane Wade ... even though the Pistons won the championship in Darko's rookie season and came within one game of a repeat title last season.

Yet, even if Milicic had established himself as a rotation regular under Saunders, it's doubtful the Pistons could have afforded to retain him beyond this summer. With Ben Wallace bound for free agency in July and Chauncey Billups expected to seek a lucrative contract extension before becoming a free agent in the summer of 2007, Detroit also needed Cato's expiring contract ($8.6 million this season) to create the salary-cap space to re-sign both comfortably and keep together its vaunted starting lineup.
