"Lovett, 64, moved into the Eagles’ scouting department in January after being replaced as the team’s defensive backs coach, a position he held for two seasons. His hiring reunites him with California defensive coordinator Art Kaufman. Lovett coached defensive backs at Texas Tech in 2012 when Kaufman was the Red Raiders’ defensive coordinator. The two also coached together in the same roles at Mississippi from 1995-98."
Lovett previously served as Philadelphia's defensive backs coach during the past two seasons. The Eagles' secondary obviously struggled during that time. The Eagles allowed the most passing yards per game in 2013 before allowing the second most in 2014.
Instead of simply firing Lovett, the team moved him to the player personnel department as a pro scout. Former Denver Broncos defensive backs coach Cory Undlin was hired by Philadelphia to replace Lovett. Eagles players didn't seem particularly fond of Lovett and they're already raving about Undlin.
