Probable Cause
The R10/12 controller issued an improper vector and descent clearance to the GII that put the airplane on a coverging flight path with the B737. Contributing to the incident was the failure of the FAA's training program to correct ongoing controller performance deficiencies before certifying the D10/12 controller to work without immediate supervision.
