Week 1 of the NFL season brought plenty of surprises and the second week will give us an awful lot more information about whether those opening performances were indicative of what teams and players will look like all season, or if they were simply an early season mirage.

For fantasy players, the opening weeks can be difficult to navigate through as you try to determine what performances are for real, who will bounce back to be better, and who will fall off to be worse long term. Most of the prominent fantasy sites have weekly projections based on past performance, opponent ratings, and more, but the formulas for coming up with those ratings can vary pretty wildly, as evidenced by some very different weekly projections and ratings depending on who you look at.
