ENGLEWOOD, Colo. –- With just over a month to go until the NFL Draft gets underway, the on-campus pro days are in full swing.

The Denver Broncos have dispersed their inquiring scouting minds both near and far. But this week there are several stops on the campus tours that will be of particular interest for the Broncos.

Friday’s schedule across the football land includes California-Berkeley, Arizona, Brigham Young and Michigan. And Ann Arbor will be a popular stop, with a long list of Wolverines' prospects that includes safety Jabrill Peppers and tight end Jake Butt – he tore his ACL in the Wolverines’ bowl game – but for the Broncos wide receiver Amara Darboh is an intriguing player for a team with some room on the depth chart at the position.

A native of Sierra Leone, his family left the war-torn nation when Darboh was in elementary school. He since has become a U.S. citizen. He carries himself with a physical toughness on the field and plays with the composure of a player who understands bigger issues in life.

From a football perspective this is an ascending player who has worked well in Jim Harbaugh’s pro-style offense. At 6-foot-1 5/8-inches tall and 214 pounds, Darboh ran an official 4.45-second 40-yard dash and continued to show improvement in each of his seasons at Michigan with 57 receptions for 862 yards and eight touchdowns as a senior.

“I’m very coachable,’’ Darboh said in recent weeks. “And also I take practice just like the games. I think it’s important to practice hard because then it makes the games easier. And especially as a wide receiver you want to run fast and get the timing right with the quarterback throughout the week so the game is not different and he doesn’t have to guess what speed you’re going.”

For the Broncos Darboh’s size and work down the field make him a player worth a long look. The game video showed Darboh had at least one catch of 30 or more yards in seven of Michigan’s first nine games this past season, and those are the kind of impact plays that get a guy noticed.

And scouts throughout the league have been told he practices with some fervor, so this is a player who is going to show up for work, which could sneak him into the draft’s second day.

“Off the field, my knowledge of the game, that I understand the game of football and I’m willing to put in the extra work and I have already put in the extra work to learn concepts and they can feel comfortable putting me at any position out there on the field,’’ Darboh said. “And on the field, just that I’m a natural. I’m a natural at wide receiver. I can catch naturally, run routes naturally, and I’m an athletic guy.’’

One of the issues the Broncos have discussed this offseason in their review of the team's offense is how to stress opposing defensive backs more than they did this past season with Demaryius Thomas and Emmanuel Sanders leading the way. Part of the solution will be how Thomas and Sanders are deployed in the offense.

And part of the solution will be adding some impact to the depth chart as well. In short the Broncos need a third or fourth player to emerge as targets in the offense who can force defenses to make decisions in coverage.

The Broncos saw plenty of defenses double both Thomas and Sanders, but the Broncos also didn’t take advantage of man-to-man matchups they did get on those players and others when they had the chance.

For his part Darboh has the look of a player who will produce in the NFL above the expectations that come with this draft slot. And his size, athleticism and game-day toughness should give the Broncos plenty of pause.
