The Lions have agreed to a four-year, $26 million contract with defensive end Kyle Vanden Bosch.
Schwartz was waiting outside of Vanden Bosch's home when free agency began on Thursday night.
" 'I could be anywhere in the country right now, and I'm on your front step because you're the guy I want,' " Vanden Bosch said Friday morning relaying Schwartz's message. "He's a great coach, and last night he was a great salesman."
Schwartz worked with Vanden Bosch when he was the Titans' defensive coordinator.
