The Chicago Bulls have cleared Derrick Rose for 5-on-5 practice, but they have not cleared him for any real games yet. As seen in this video, Rose is dunking fairly easily with a bit of a running start. However, as Heather Cox mentions in the video, the true measuring stick for Rose's return is whether or not he can explode without a running start.
Having said that, this video is good evidence that the return of the herky-jerky Rose is certainly within the realm of possibility this year. And since the Chicago Bulls will extend their play into the playoffs, this will only buy more time for Rose to return back on the court.
