Trey Marshall’s comfort level.

Quick-hitting Broncos topics as training camp approaches, with the report date July 18:

When the organized team activities began in mid-may, coach Vic Fangio said the goal was to practice about 90 percent of the defensive plays.

On offense, coordinator Rich Scangarello didn’t put a percentage on what he called, but it was enough to give the coaches an idea of how the players fit into his scheme.

“(The second) year, it’s always a little bit easier, but there was a lot of volume (in the offseason program) just because we wanted to find out what guys could do in our offense and what their best strengths are,” Scangarello said.

Now that they know how much the players have absorbed they will take a slightly altered approach when camp begins. Yes, the volume will remain indepth, but the process will move quicker.

“When we come back for fall camp, we can hone in on the plays and schemes that are besttailored to the personnel we have and (quarterback Joe Flacco’s) strengths and everyone’s strengths. I’m excited about that,” Scangarello said. “Now we have a bit of direction so we can tighten it up.”

Safety Trey Marshall entered camp last year as an undrafted free agent who eventually ended up on the practice squad and was activated for the final two games.

Marshall’s climb appears similarly tall when camp opens July 18. There is a logjam at safety behind starters Justin Simmons and Kareem Jackson and top reserve Will Parks that includes Marshall, Jamal Carter, Su’a Cravens, Dymonte Thomas, and Shamarko Thomas. Marshall, though, is confident. “I feel really comfortable in the new system,” he said. “It’s a lot easier to play in because I’m able to relax and just play the game of football with my instincts.”

What did he learn last year? “(The importance of ) studying because everybody is talented so the only way to separate yourself is to know the game,” Marshall said.

Marshall will benefit from the Broncos’ extra preseason game (Aug. 1 vs. Atlanta) because the starters are unlikely to play.

“I look at that as a good thing — it’s another opportunity to prove myself,” he said.
