It was interesting to note after Edmonton lost to Saskatchewan how Ritchie blamed "the 13th person".
I'm paraphrasing but he said something like "We have to stop being beaten by the 13th person out there on the field and the 13th person is us."
The 13th man thing, which is still used in CFL advertising, is one of the league's main themes and now Ritchie has gone and used it in a negative connotation (albeit with person replacing man). I hope it doesn't catch on with other coaches.
I'm not sure what Ritchie was getting at. I think he was trying to say that all the mistakes the Eskies were making (drops and fumbles) were the 13th person.
It's also auspicious that he would start using the term in Saskatchewan of all places.
