To be fair, Mort saying specifically "Col Rogers [sic] (driveclub) is about failing to deliver" in this situation a claim of factual behind-the-scenes happenings. If Putty is right that Rodgers left specifically for personal reasons, it's reasonable to think of those as being mutually exclusive explanations. Or at least very different characterizations.
Truth is there are always two side to a story , Stig also left SSM but we all know the reason for that .
Sometimes there can be more than one reason things happen .
