Here's a look at how some of the top rookie running backs and wide receivers are performing so far.
Adrian Peterson, Vikings: He overcame a hip pointer to play in the preseason opener against the Rams and rushed for 33 yards on 11 carries. Peterson is due for a healthy workload even while splitting time with Chester Taylor. He's also going to get a lot of defensive attention, so don't expect statistical consistency. He's shaping up to be a quality pick late in the fourth round of 10- and 12-team leagues.
