Wikipedia:Articles for deletion/Phil Mathews
I read the phrase "Examples would include head coaches, well-known assistant coaches, or players who: ..." as using a serial comma, meaning the entire phrase is subject to the list following for which the subject does not meet.  If you feel GNG is met, which it may meet with new evidence, then please add to article.  As many of those articles seem to be about him getting hired or fired from a club, I would be wary of  which I believe those may fall under
