I don't think Mario was a bad signing, but I do think that our attitude toward him turned when his attitude toward effort turned. For whatever reason, Mario ceased to perform and we were glad to see him go. Superstars should never underperform to the point that fans cheer for their departure. Even if the physical skills diminish, the effort and character should be resilient. Evidently, in Mario's case, something was lacking. Fans are entitled to point their collective finger at Mario's effort.
