It was basically Vince's way to say "FU" to Blanchard since he and Arn had given their notice right before Halloween of '89 and their last date for the WWF was Survivor Series 1989. Ironically enough, because of the failed drug test, JCP/WCW decided not to bring him in and voided his contract so only Arn went back. Of course since Tully's contract was voided and they were no longer going back as a team, Arn had to sign a new contract for less money than the original contract. That cocaine failure basically ended his run with the WWF and JCP/WCW
An interesting note, back in '89 when TV and markeing was close to nil for JCP/WCW, Arn Anderson and Tully Blanchard were each signed to a 3 year, $750K contract. Thinking about that and comparing it to some ofthe guys today, that's crazy money they made back in the day.
