ENGLEWOOD, Colo. -- A closer look at the positions the Denver Broncos could target at the NFL combine in Indianapolis:

Positions of need: If you judge by what’s been said and written about the Broncos since around Halloween, there is no need on the roster other than quarterback. After a 5-11 finish, it's clear the Broncos need plenty of things, but a solution at quarterback certainly leads the way.

Their coaches spent a week working with the North team at the Senior Bowl in January -- a group of quarterbacks that included Oklahoma's Baker Mayfield, Wyoming's Josh Allen and Washington State's Luke Falk -- so they got a jump on the process. If the Broncos take a deep dive in free agency at quarterback, it will impact where they look in the draft, but they are looking to reconstruct the depth chart at the position.

But they’re also thin on the offensive line -- particularly at guard and right tackle -- and at wide receiver. And they could need help in the secondary if cornerback Aqib Talib is a salary-cap casualty.

Three players the Broncos should focus on at the combine

Lamar Jackson, QB, Louisville: The Broncos will give all of the top quarterbacks a long look, including the guys they coached at the Senior Bowl as well as Sam Darnold and Josh Rosen. Regarding Jackson, he was simply too productive (two 3,500-yard passing seasons, two 1,500-yard rushing seasons and 119 career touchdowns), too athletic, and too clutch in big moments to ignore. In the right hands, Jackson’s throwing mechanics can be cleaned up, and he has shown the ability to work through his progressions while working in the shotgun or under center.

Taven Bryan, DT, Florida: Bryan has the potential to be the kind of interior pass-rusher teams covet. He has a dominant first step and has shown power as well as top-tier athleticism at the point of attack. A late bloomer of sorts, he does need some work in keeping blockers’ hands off him and he needs to expand his assortment of countermoves in the pass rush. Bryan is working with Denver-area trainer Loren Landow before the draft. Landow will begin his new job as the Broncos' strength and conditioning coach after he completes his pre-draft commitments.

Rashaad Penny, RB, San Diego State: At 5-foot-11, he checked in at the Senior Bowl at 224 pounds. This is a big back who can move and provide some impact in the passing game -- he had a 73-yard catch-and-run touchdown in the game. He rushed for 2,248 yards this past season. His 175-yard effort against Stanford as well as his 221 yards on just 14 carries against Army to close out the season offer a glimpse of the potential.
