Rookies are kind of difficult to gauge.
You could have a rookie come out and play like Adrian Peterson, who in his first year was Pro-Bowl worthy.
And then you have the Ryan Leafs of this world.
It just isn't easy to define success as a rookie.
What it really boils down to is this: It's all relative to the team and the situation.
But taking all that into account, there are several rookies in the NFC West who figure to have big impacts.
And let me define impact very quickly. When I say impact, I mean production.
I mean changing the success of a team.
I mean being involved in how the team plays.
Now obviously I have to include the pictured Sam Bradford in this list, but what about the other nine?
