"In my opinion, we've already drafted a quarterback, first round a couple years ago. So we've tried that," Marshall said, according to Kevin Patra of NFL.com.
Marshall was referring to Paxton Lynch, who has played in just five games since being selected by Elway with the 26th pick of the 2016 draft. The light workload is a result of poor play and consistent injuries since entering the NFL.
"I think he's going to get a free-agent quarterback. I think he's going to go spend some money and fix the position, you know, because it's kind of a toss-up with these rookie quarterbacks. You never know," Marshall said.
Even though the Broncos are equipped with the No. 5 selection in this year's draft, Marshall has his eyes set on a particular veteran.
"I mean, there's a couple guys out there," Marshall said. "You know. We played against a guy in Week 16 that was pretty good."
Although the Redskins remain interested in Cousins and will have the first opportunity to retain his services for 2018 with the franchise tag, Marshall isn't the lone Broncos defender hoping to upgrade the team's woeful passing offense with the Washington pivot.
"A lot of teams would kill to have a quarterback like that," linebacker Von Miller said.
