Boy, you have to love what Peterson brings to the table.
He's athletic, fast, seems like a nice guy off the field, etc.
So let's daydream for a moment shall we?
Short-term impact: Peterson will have a bit of a learning curve in the NFL, as good as he is.
Why? Well, because he'll be going against much better receivers.
The good news is though that he's faced more NFL-ready receivers than the average cornerback, as he played against both AJ Green and Julio Jones.
As to when he starts, I think he will start the week after the bye for the Cardinals, or Week 7, (our sixth game) against Pittsburgh at home.
Either way, I think he doesn't start the season but takes Greg Toler's place before the season is out.
And I think he does the same with returning punts.
If the NFL weren't in a lockout struggle, I might say he does those both sooner because of his immense talent.
Long-term impact: Speaking of his immense talent, if the Cardinals can have him the desert for 10 years, I'd say we are blessed.
But, really, I do think he's a future Pro Bowler, which is scary because the Cardinals have another corner in DRC who's a potential perennial Pro Bowler (and already been to one).
And in fact, if we are talking best care scenario, the Cardinals will have the best corners in the league within two years.
Not to mention maybe the best secondary if Adrian Wilson can play a few more years, and Kerry Rhodes stays around.
