First time IDP - need some help with Keepers

Hey All,

I jumped head first into IDP, taking on a 12 team Dynasty roster that had been abandoned in a standard scoring format. The team is pretty bleak, but I need to pick 11 Keepers. Any Help would be awesome, here is the current roster. All scoring is basic yahoo points system, only they cut the totals in half. So if a tackle was worth 2 pts, its now 1pt.
