The Denver Broncos are in the midst of an offseason of change. After two straight disappointing campaigns, the team fired head coach Vance Joseph replacing him with Vic Fangio formerly of the Chicago Bears. They made the biggest trade of the offseason thus far when they traded for quarterback Joe Flacco.

The Broncos have plenty of other holes to fill, and should continue seeking trades.

Here are three names that make sense as potential targets.

Wide Receiver DeSean Jackson

The Broncos have invested a lot in improving their receiving corps. They just announced they would pick up Emmanuel Sanders' option for 2019 and retain him for at least one more year. They also drafted both DaeSean Hamilton and Courtland Sutton in last year's draft.

While they have a solid group of receivers, they need a burner. Jackson would provide them with something they don't currently have, elite speed. Flacco has a big arm, and the Broncos need someone who can get behind defenses and keep safeties honest. Jackson is under contract in Tampa Bay, but reportedly wants out.

Quarterback Josh Rosen 

The Broncos have Flacco now, but that doesn't mean they're done pursuing quarterbacks. They've still been heavily linked to Missouri quarterback Drew Lock, and are considered somewhat likely to take a signal caller with the tenth overall pick. But instead of using an early draft pick on a quarterback, they should trade for a young one.

Rosen is reportedly being shopped by the Arizona Cardinals if they take Kyler Murray, and the Broncos should be interested. Broncos general manager John Elway spoke highly of Rosen during last year's draft process and has always been a fan. Rosen is reportedly only likely to fetch a mid-round pick, which is a small price to pay for a young quarterback with a ton of potential.

The UCLA product could develop behind Flacco for a year, or beat him outright in camp this year. Flacco's contract has no guaranteed money left, so Denver isn't tied to him at all. Trading for Rosen makes a ton of sense, and he has the potential to be a real quarterback of the future unlike Flacco.

Wide Receiver John Ross 

If the Broncos don't get someone like Jackson, they should turn to Ross.

Ross is also a burner, who can provide the vertical threat the Broncos need in a similar way. The 24-year-old wideout is also similar to Rosen in that he's a very talented young player with a ton of potential who can be had for very cheap. Ross is being shopped by the Cincinnati Bengals, and can likely be had for a late-round pick.

A team like the Broncos that is desperately trying to get younger would be the perfect fit. Ross needs a fresh start, and could revive his career in Denver.
