Defensive Backs should be the last IDP position you draft as they have the biggest variance year to year. These draft rankings represent you best options for the 2015 season, especially the tier 1 options.
Tier 1
1. Harrison Smith - MIN It is hard to argue his number 1 position. Big plays tackles and steady. You get it all with Harrison Smith
2. Morgan Burnett - GB Burnett benefits from a weak LB group in GB he led DB in solo tackles last year and I expect the same this year
3. Reshad Jones - MIA Jelanie Jenkins and Reshad Jones are the only two tacklers in Miami so I expect a repeat performance in 2015
4. Eric Weddle - SD If you don't like streaming a DB week to week grab Weddle he is as steady as you can get
Tier 2
5. T.J. McDonald - STL I think T.J McDonald would be the number 1 safety on any other team but the Rams have a very competent LB group so his tackles take a bit of dive
6. Jonathan Cyprien - JAC A great DB for tackle heavy leagues. Just don't expect too many big plays
7. Landon Collins - NYG Landon Collins has huge potential in NY he will almost be a LB!
8. T.J. Ward - DEN
9. Antoine Bethea - SF
Tier 3
10. Ha Ha Clinton Dix - GB
11. Donte Whitner - CLE
