JACKSONVILLE – Gus Bradley's focus was familiar Thursday.

It was his listeners who were a bit unusual.

Bradley, the Jaguars' third-year head coach, did speak about fundamentals and football Thursday, but instead of NFL players, his audience was area high school football coaches.

Bradley spoke for a half hour at the annual Jacksonville Jaguars High School Football Coaches Clinic at EverBank Field Thursday, an event at which multiple Jaguars assistants, including offensive coordinator Greg Olsen and defensive coordinator Bob Babich, also spoke.

Bradley said attendance at the event was up from 115 a year ago to 200.

"It's always good to see the numbers go up," Bradley said shortly after noon Thursday. "We're just looking each year to try to make improvements on it."

Bradley said an emphasis at the clinic this year was in the basics.

"This game has evolved to where it's all about the fundamentals," Bradley said. "I think it always has been, but we want to make a renewed emphasis on that – how to tackle, how to do some of the fundamental things: blocking, tackling, getting off blocks.

"We hope to make an environment where we challenge them and they challenge us and we can all improve."

Bradley on Thursday also said there was nothing new regarding center Steve Wisniewski, an unrestricted free agent who visited the Jaguars on Wednesday.

"We'll have more conversations about that, but right now, it's in a holding period," Bradley said, adding that there was "nothing that I'm aware of" regarding free-agent wide receiver Greg Jennings.

Wisniewski, a second-round selection in the 2011 NFL Draft by Oakland, started 61 games in four seasons with the Raiders. Jennings, a second-round selection in the 2006 NFL Draft by Green Bay, has 552 receptions for 8,083 yards and 63 touchdowns in a nine-year career with the Packers and the Minnesota Vikings.

Bradley also addressed the team's fullback situation, with the team currently having no players at the position under contract. The Jaguars released fullback Bradie Ewing Tuesday.

Bradley said the team is considering carrying more tight ends to play the role previously played by a fullback.

"We are looking at having an extra tight end to where we've had in the past," Bradley said. "If there is a fullback out there that is meeting our needs and can do some of the things that we're going to ask him to do, we will always be open to it."
