Ryan, what’s the situation with DeMarcus Walker? Is he likely to make the final 53? I think coach Vance Joseph and crew handled him very poorly (as they did so many others … sigh). Thanks for all your great work.

— Mike Koonce, Bend, Ore.

Walker, a second round pick in 2017, has two sacks in 13 career games. Last year, he barely made the roster when the Broncos decided to keep him as a sixth defensive linemen instead of veteran Clinton McDonald. Problem was, the Broncos had only five active linemen on Sundays and Walker was limited to three games. The math again doesn’t work out for Walker if new coach Vic Fangio sticks with five active linemen (Derek Wolfe, Adam Gotsis, Shelby Harris, Zach Kerr and rookie Dre’Mont Jones). Walker will start training camp on the roster bubble and let’s face it, the only reason the Broncos haven’t given up on him yet is because of his draft status. If I had to bet a buck, I would say Walker makes the initial 53-man roster.

After all the OTAs, my primary concern heading into the season is inside linebacker. The personnel is the same as last year, which was not pretty. Arguably our biggest position of need and we did nothing to address this in the draft. Are we hoping that scheme or the waiver wire is going to do the job?

— Allan Tremblay, Edmonton

The only change at inside linebacker was the departure of Brandon Marshall, whose contract option was declined and he eventually signed with Oakland. Todd Davis and Josey Jewell will start camp as the base-down starters and are likely to hold those roles entering the Week 1 opener at Oakland. But what about the sub package situations? Brief looks during the off-season program suggest that Davis/Jewell are Fangio’s choice if the Broncos play nickel. That means Fangio is counting on scheme adjustments to improve the linebackers’ ability to cover tight ends. One camp sub-plot is rookie Justin Hollins, who was drafted as an outside linebacker but also learned the sub-package inside linebacker spot.

Adam Rank has the Broncos going 2-14 this year? Obviously he spends a lot of time in Colorado enjoying the plant life. I see a big step forward this year with some of the changes made in the offseason. If Joe Flacco can play to form, I see eight to possibly 10 wins if breaks go our way. Thoughts?

— Jeff Axline, Jefferson, Md.

Adam’s goal at this time of year is to throw out predictions that generate web traffic and attention. Mission accomplished with his Broncos forecast. It’s tough for any team in the NFL to go 2-14 — the organization basically needs to have a system-wide, season-long breakdown. Heck, as flawed as last year’s Broncos team was, they still found a way to win six games. Now, about a taking a big step forward. Flacco is obviously a key in terms of pushing the football down the field and making the offense functional. This defense is set up to stop teams on a consistent basis. If the Broncos can score just a few more points a game, some of those 2018 close losses will turn into 2019 narrow victories.

Ryan, I saw the Broncos released their all-time Top-100 team. Which of the team’s young stars has a shot at cracking the list in a few years?

— Mike, Sheridan

Four current Broncos were on the top 100 team, which was posted on Monday: Outside linebacker Von Miller, defensive end Derek Wolfe, cornerback Chris Harris and receiver Emmanuel Sanders. An easy pick down the road is outside linebacker Bradley Chubb. Maybe receiver Courtland Sutton if he develops into a No. 1 target.
