Over the last three seasons, the Bulls have cycled through a bundle of shooting guards, or reasonable facsimiles of shooting guards, in trying to find just one that combines “B”-level shooting, defense, passing, and good health. They’ve tried John Salmons, Keith Bogans, Kirk Hinrich, Ronnie Brewer, Kyle Korver, Richard Hamilton, and Marco Belinelli, and none have quite provided the ideal combination. Chicago, when whole, has a legit top-10 player in Derrick Rose, a very good all-around wing in Luol Deng, and a prized collection of skilled big men. They don’t need a star at shooting guard; they just need someone who can do everything at a decent level without compromising the team in any one area.
