You guys are delusional. Thomas Robinson, the 5th pick in the same draft, has been traded twice already and neither trade has involved a first rounder. You reallllly think Marquis Teague is more valuable than Robinson? I'd trade Teague for Robinson in a heart beat. Robinson was moved to clear payroll, but it's not like his salary is insane, he's still on the rookie scale. Teague has done nothing in the NBA to warrant a first rounder.
One of those trades was to make room for Dwight so and the other they had an absolute log jam and he wasn't getting playing time. Like others have said, there's a difference between trading a guy because you don't want him and trading a guy because someone else wants him. dabulls1 said it perfectly.
They aren't the ones trying to trade him. Utah trades whatever (within reason) Chicago wants or Teague stays in Chicago.
