Bradley will be ready to deal with any obstacles that come his way.

Bradley is a man who shows through triumph and also through difficulties, according to his former teammate and current employer, the JacksonvilleJaguars. He is the same guy when things are going well. That is what he told me. Those are people that you want to stay near and dear to, not just in this football realm, but in life as well.

The biggest news on the Colts' side of the ball was the absence of Leonard. They can't afford to be without their best player for a long time. The team's defense depends on him.

He had back surgery this month after having back surgery a year ago to repair his left ankle. The Colts didn't know how bad Leonard's back pain was because he hadn't done any on-the-field activities.

Even if he misses most of training camp, the Colts will still take a methodical approach. It's worth being patient with Leonard because through his first four seasons in the NFL, he's totaled 537 tackles, 16 forced turnovers, seven fumbled possessions, seven turnovers and 11 picks.

More people play on the sports network. There is a fantasy football game. If you sign up, you'll get free.

After the departure of DC Matt Eberflus, Leonard will be the leader of the second level of the Colts' defense. Several members of the Colts staff were with Eberflus.

Bradley had to add pieces to his staff with the Colts because he was the head coach in Seattle when the 'Legion of Boom' unit was led by Richard Sherman and Earl Thomas. John Fox is the team's senior defensive assistant.

Frank Reich said that he knew a lot about the man because of his relationship with Nick and Philip, who were with him for a long time. He's a guy who meshes with our culture. He is going to help us elevate by bringing a dynamic to our defense. Over the last four years, we have played some really good defensive football, and I think we will continue to improve.

Bradley, who was with the Las Vegas Raiders last season, will be working with a unit that has a lot of skill players on the line, at linebacker and at the corner. The line will include Kwity Paye and DeForest Buckner. Gilmore was the defensive player of the year in the National Football League. The two key pieces are expected to help a defense that was 16th in the league in yards allowed and second in the league with 33 turnovers.

Cooper Kupp can be helped by Allen Robinson.

• Dennis Allen 'keeping the DNA the same'

• Dick Vermeil's unconventional HOF career

Four of the five seasons in which Bradley oversaw the defenses, they finished in the top 10 in fewest yards allowed. The Colts will have to play at a high level to deal with the quarterbacks on their schedule.

"Same tree, a little different flavor, but still the emphasis on effort, speed, Fundamentals, taking the ball away, all those things that we've talked about in the past, we'll do with Gus," Colts general manager Chris Ballard said.

Strength and speed fit perfectly with the way Bradley runs his defense. Bradley's defense is pretty simple. While sticking with a 4-3 scheme, he will sometimes mix it up to allow free runners to get to the quarterback.

"I think you won't see the D-line playing or reacting to the blocks, moving with the blocks and things like that." It will be similar to how we are on our tracks. You will see us more in the backfield if the guys are embracing the scheme.
