I have ran a league on Yahoo for 12 years now. I personally keep a spreadsheet of every match up score and end of season statistics. This allows me to be able to tell the league specific match up stats. This weeks looks like - "Jon is 7-2 all time vs Matt but they are 1-1 all time in playoff match ups. Matt is 2-1 in finals and this is Jon's first finals appearance" It would be cool if Yahoo displayed stats like that for the match ups or we at least had easy access to pull that sort of data.
