And that they could spend those dollars elsewhere to fix some holes in the depth chart and somehow replace Decker in the offense.
For it all to work as they hope, those major investments -- DeMarcus Ware, T.J. Ward and Aqib Talib -- will certainly have to lift the defense. But for the plan to go from drawing board to deep in the postseason, preferably a return trip to the Super Bowl, the Broncos will simply have to be right about Emmanuel Sanders.
The wide receiver was among their top offensive targets when the Broncos made their wish list before free agency opened. They see him as a versatile, fast, quick-twitch receiver who is ready to benefit from Peyton Manning's presence behind center.
Or as John Elway has put it: “When we looked at him, and I've said this to our guys, too, you saw a guy who has only scratched the surface. He's young with a lot of potential, even on top of what he's already done."
Decker's departure leaves a fairly large gap in what the team did on offense last season. At least in the regular season, anyway. Decker's totals dipped in the postseason, as Manning focused elsewhere, but Manning looked Decker's way 137 times in the regular season. Demaryius Thomas was the only Broncos receiver targeted more in 2013. Thomas isn't going anywhere in the pecking order. The Broncos see him as a special player who still has room to grow, even after his 1,430-yard, 14-touchdown season in 2013.
Tight end Julius Thomas was the fourth-most targeted player in the Broncos' offense last season. He missed two games with a knee injury in the regular season, but was far more active in the playoffs. He will be a bigger part of the offense in the coming season.
Wes Welker missed the final three games of the regular season while recovering from a concussion, but he was the third-most targeted player in the offense.
Sanders' ability as a slot receiver, as well as his ability to line up out wide, should help the Broncos create more matchups to get Julius Thomas the ball down the hashmarks. It was Sanders' ability to line up all over the formation, as well as his after-the-catch performance, that made him the Broncos' top target on the offensive side of the ball once free agency opened.
Sanders had a career-best 67 catches last season, but the Broncos believe he can go far north of that total in their offense, given the choices Manning has before the ball is in the air. Still, all of those plans are built around the idea that Sanders has to be up for the job, too.
The Broncos may feel like Sanders is quicker in the short area, faster in the open field and better after the catch than Decker. But Decker was on the finishing end of touchdown passes 24 times in the two seasons he played with Manning.
Some of that was Manning's ability to work the Broncos' scheme and find the favorable matchup. There is a long list of receivers who have put up career-best numbers with Manning. Still, Decker's production will have to be replaced. The Broncos lined up in a three-wide receiver set on 73.6 percent of their offensive snaps last season.
The Broncos lined up in a three-wide set even more than that as the season wore on, including all but one snap against the San Diego Chargers in the divisional round. And even with their intentions to run the ball better next season, Sanders will be key in how successful the Broncos are in making the transition from how the formation looked in 2013 to how it will look in 2014.
Questions surround Welker, who enters the season with two concussions in 2013 to go with a concussion history from before he signed in Denver. There is always a chance he will miss some time in the coming season.
In the end, the New York Jets put a $36.25 million contract in front of Decker and the Broncos signed Sanders to a $15 million deal. The Broncos did their comparison shopping, looked at the balance in the checkbook and made Sanders their choice.
