"He's just that type of player," Miller said Tuesday on ESPN's First Take (h/t Nicki Jhabvala of the Denver Post). "He not only would be a difference-maker to my team, but any team he goes to in the National Football League. It's an instant upgrade, leadership, he can throw and make all the passes on the field. So, yeah, when you get a guy like that, you're automatically in Super Bowl contention."
The Broncos could certainly use an upgrade at quarterback. Trevor Siemian, Brock Osweiler and Paxton Lynch combined to throw for 3,668 yards, 19 touchdowns and 22 interceptions in the 2017 season, completing just 58.7 percent of their passes.
Given that level of play, the Broncos unsurprisingly went 5-11 and missed the postseason for the second straight season after five straight trips to the playoffs and a Super Bowl title in the 2015 campaign.
Miller said whatever the team decides to do regarding the position, general manager John Elway has his support:
"I think the decisions that John has made have put us in championship position. You can't go out there and just spend all types of money every year. John has been great with that. Our front office has been great with that. Me and Mr. Elway, we're tied at the hip, whatever decisions that he makes, whatever direction he takes the organization, I'm right there with him."
Elway, meanwhile, has suggested the team's issues ran deeper than quarterback play, per Jhabvala:
"First of all, I don't think our guys played to their abilities on the defensive side. Offensively, I think that we got better, but I don't know that it was a good fit for us. I don't want to point fingers at anybody, but we had a bad fit there. So we tried to correct it and it was a little bit too late. So this year we'll go into this offseason with one plan and stay with that plan and it's a system that's going to fit especially the quarterbacks a little bit better."
Money will be a factor in any pursuit of Cousins, who is set for a major payday. The Broncos have around $23.9 million in cap space, per Spotrac.com, far less than other potential Cousins suitors like the Cleveland Browns ($108.9 million in projected cap space), New York Jets ($92.1 million) and Minnesota Vikings ($48.1 million).
That could prevent the Broncos from landing the top free agent on the market. But Cousins would absolutely represent an upgrade and would return the Broncos to at least postseason contention given the other talent on the roster, including Miller.
