The strength of Bill Belichick’s defense lies in its secondary.

There’s no doubt that the Patriots cornerbacks and safeties are among the league’s best. But where do the rest of the positional groups stack up as New England heads towards training camp?

Here are all 10 of their groups ranked from top to bottom:

1. Cornerbacks

Departed: None

Under contract: Stephon Gilmore, J.C. Jackson, Jason McCourty, Jonathan Jones, Joejuan Williams, D’Angelo Ross

Free agent addition: None

Draft addition: None

Undrafted free agent: Myles Bryant

It’s not just the reigning Defensive Player of the Year, Stephon Gilmore, that lands this group the top spot, but the depth that compliments him, too.
