CB, while I hate to find fault with these threads, since I think will spark some great discussion, I have to question the reasoning behind using yahoo's default scoring system to come up with the rankings. Now, I realize that you're looking for a "standard", and since yahoo is the most popular FF site I can see the logic behind using their default system, but the truth is that once most players graduate from their first week of FF noobishness they move past yahoo's arcaic TD-heavy scoring system.
A very very very standard scoring system has been adopted among the vast majority of leagues involving players committed enough to FF to visit this site:
25 yards per point
4 points per TD (6 points per TD will also do fine here)
10 yards per point
6 points per TD
I only bring it up because it can vastly change the rankings. I doubt anything more than a minority of the people here play in a league where Stephen Davis ranks 7th in scoring amongst RBs. In leagues with the "standard" scoring he ranks 11th. Likewise, you won't find a lot of leagues where Davis ranks ahead of TJ and Westbrook. Not a huge difference, but noteworthy nonetheless.
