Yep, it is extremely hard to put rookies on a list like this. I know Eric Weddle plays for the Chargers, but is he going to get any playing time, or is he a starter?
my list would probably be:
1-sean jones (bias kickin in
)
2-Bob Sanders
3-Donte Whitner (buckeye bias!)
4-Polamalu
5-Madeui Williams (he's also underrated in my opinion as well)
i believe ed reed, and roy williams have established themselves as veteran forces in the league, and set the standard at the safety position, I see the 5 guys on the list above as players who will take over for reed and williams. Polamalu is well on his way to doing this.
