I don't think it says anything about Mannion...

The game was out of hand early. I think leaving Keenum in for the duration was more a statement to the 'team', and Keenum himself of course, - that the organization will stick with them as long as they can... no quick trigger fingers. Instilling a feeling of security for the team.

Now whether or not that was the right call? I don't know... the above has merit, but in this case? I don't know. - JamesJM
