The most direct trade package that the Chicago Bulls could pull off with the Clippers would be two players on the trade block for each team. In that report from the LA Times that mentioned the Clippers were targeting Young in the first place, it also noted that they were looking to possibly deal out the former Portland Trail Blazers wing Maurice Harkless.
Not having his best season so far, the Clippers are making Harkless expendable. With both Thad and Mo having poor starts to the regular season, maybe a change of scenery is good for each player. The exchange of contracts is about equal money too. Harkless only has one year on his current contract, though, while Young has three.
So far this season, Harkless is averaging 5.4 points per game, 3.6 rebounds, and 1.1 assists while shooting around 49 percent from the field and 35 percent from beyond the arc. Meanwhile, Young is averaging 8.8 points per game, 4.5 rebounds, and 1.8 assists, while shooting 39.7 percent from the field and 32.4 percent from beyond the arc.
Harkless brings a lot of factors to the table that the Bulls need, and Young brings a lot that the Clippers need. This exchange seems to benefit both sides, and it makes sense if the Clippers are already interested in dealing Harkless and bringing in Young. This would be the most simplistic, and likely realistic, of the three possible trade packages listed here.
