New Denver cornerback Drayton Florence said reuniting with former Jacksonville head coach Jack Del Rio was one of the reasons why he signed with the Broncos on Thursday.

Del Rio is Denver’s new defensive coordinator. Florence played for Del Rio in Jacksonville in 2008.

“Yes, the familiarity always is good when you’ve played for somebody and you know how they work,” Florence said in a conference call with reporters. “The system, the language is going to be familiar. So it was a good fit.”
