Roster construction is a never-ending challenge, but college football teams occasionally find a pair of outstanding teammates.
Also in the lead-up to Week 1, we checked out some of the best offensive duos in the country. Now, it's time for defenders.
The pairings are focused on players at the same position. While no team would complain about one high-end pass-rusher and safety, two star linebackers or lockdown corners are a greater strength.
Honorable mentions are Alabama corners Kool-Aid McKinstry and Terrion Arnold, Texas A&M corners Tyreek Chappell and Tony Grimes and Washington edge-rushers Bralen Trice and Zion Tupuola-Fetui.
