the offense. This poor performance led to an April 15 report that stated a much-discussed trade for Kansas City’s Trent Green was imminent, for Culpepper was unable to participate in the minicamp as he continued to recover from knee surgery. The weekend previous to the report, Culpepper revealed that the second surgery, which was designed to address scar tissue in the knee, was more serious than anyone originally divulged, and called for a rehabilitation period of 4–6 months.
