It's safe to say that the Denver Broncos took the free-agent market by storm this year, targeting the players that they wanted early and throwing down the cash to make it happen. The most notable acquisitions up front were Aqib Talib, DeMarcus Ware and T.J. Ward. They followed up that defensive overhaul shortly afterward by adding Emmanuel Sanders on the offensive side of the ball, replacing Eric Decker.
However, no team is ever really complete. There are always moves that can be made and upgrades that could change the dynamic and provide new options. For every position of strength and depth, there is another position that is thin and weak.
Opposing teams identify these positions and target them when possible. Against a weak defensive backfield, the game plan will be to throw the ball and test those players, for instance, avoiding a strong defensive line that is able to shut down the run. In this way, a good game plan can neutralize some of the best players on the other side and make the team as ineffective as its worst player.
No one knows this better than Peyton Manning. He does it on a weekly basis.
To avoid this, teams must have as much talent across the field as possible. Denver has made key upgrades and the team will look much different—defensively, at least—in 2014. However, there are still steps that can be taken to improve the team so it is less vulnerable, especially in the playoffs, when injuries make such a difference.
While the money situation will not make all of these signings easy, there are some excellent free agents that the Broncos should still target if they can make the cap space work out. With a team poised for a Super Bowl run, that's often easier since players will be a bit more flexible if they can play for a winner.
At this point, though, need is the most important factor, even when looking at depth. These players are ranked by how well they would fit a need with Denver, and not necessarily by their own raw talent.
