Kicker is a position where you should have ample options in free agency, as no one should ever draft a backup kicker. If you actually did draft a backup kicker, go cut one of them and pick up the highest-rated QB, RB or WR you can find.
Kicking performances are very hard to predict on a weekly basis -- a kicker can pick up any number of points each week, and how his offense and defense do really doesn't impact a kicker's numbers. The offense can get shut down, yet the kicker can hit three FGs and have a great game, even though his team lost 35-9. Or the offense can keep reaching the end zone, yet your kicker only ends with four or five points. All that being said, here's my best guess:
1. Stephen Gostkowski, NE vs BUF
2. Nate Kaeding, SD at OAK
3. John Carney, NO vs DET
4. Neil Rackers, ARI vs SF
5. Jason Elam, ATL vs MIA
