The Jazz should set their sights on acquiring ex-Utah guard Mo Williams, a.k.a. Kevin O'Connor's Regret.
To this day, the Jazz general manager ranks not re-signing Williams in 2004 among his biggest mistakes. The team thought Williams was OK, but it already had Carlos Arroyo and Raul Lopez, then signed Keith McLeod and Howard Eisley for the next season. That's not a special group of guards, but the Jazz didn't think Williams was special, either, or they would have kept him.
Thus, Utah became a no-go for Mo.
Unless he wants to come off the bench for the right price I don't see it. He makes almost the same as Harris right now and is obviously a huge upgrade over Chops but he's not a great fit. They could use what he brings off the bench probably especially off the ball which is where Harris would serve best as well.
