Billy Napier hired Vinnie Sunseri as Florida's new DC on Saturday. Here's what to know of the former national championship, NFL player:

Vinnie Sunseri, who played safety at Alabama from 2011-13, will replace Austin Armstrong, who left UF after two seasons for the University of Houston.

The Florida Gators are hiring Vinnie Sunseri as co-defensive coordinator/safeties coach, marking a swift transition in his coaching career.

Vinnie Sunseri always was known as an aggressive player for Alabama, as a safety running all over the place and hitting people. He's since carried that approach over to his coaching career, on Saturday accepting his second job in three and a half weeks since leaving the University of Washington -- going from the Huskies to Jacksonville State to Florida.
