What happens if on Monday morning, someone looks at a Sunday photo of that week's PGA tournament winner and notices 15 clubs in the bag (or some similar, obvious, unquestionable rules violation)? Just to make it messier, assume two or more players were tied for second, one stroke behind the winner.
I'm not sure if this is a rules of golf question, a PGA question or a tournament organizer question -- but sooner or later, it's going to come up.
