You're right that my post would be more interesting with additional data.  As you noted, the data over time would be interesting.  I'd also be interested to combine WR, CB, S, RB, and ATH.  Those guys cover a total of 7/22 positions on the field.  I bet if you add up the 4-stars at those positions, you'd see more than 1/2 of the total 4-star rated players even though those guys account for about 1/3 of the total players on the field and even though those guys have a disproportionately small impact on the outcome of the game relative to the guys who play DL and OL.
