NASHVILLE, Tenn. -- Tennessee Titans quarterback Marcus Mariota gathered up his pass targets and threw with them Friday, Saturday and Sunday in Nashville in advance of the official start of the team’s offseason program.

The team can’t start working at the facility in groups until the offseason program officially kicks off on April 18.

Harry Douglas and Dorial Green-Beckham told me the group threw and ran routes together at Nashville’s Father Ryan High School, which has become a popular spot for collective offseason work.

Green-Beckham said “we were all there.” which suggests a group that also included free-agent addition Rishard Matthews, Kendall Wright and Delanie Walker. I don’t know about backup quarterbacks Zach Mettenberger or Matt Cassel.

It was the group’s first get-together at Father Ryan this offseason.

Titans GM Jon Robinson said he’d heard some guys got together.

“It shows you that there is a group of guys committed to winning, that want to buy in to the type of football that we’re going to play,” he said. “Doing the little things and going above and beyond, sacrificing your own personal time for the Titans, that’s what we want to be about.”

UPDATE, 2:42 p.m.: I've learned Justin Hunter and Mettenberger were part of the workouts.
