One of the key challenges for NFL teams is to build a roster of talented players while staying within the constraints of the salary cap. This requires careful management of player contracts, as well as strategic decision-making when it comes to signing free agents, making trades, and drafting new players.

Teams that are successful at managing the salary cap and building a balanced roster have a better chance of sustained success over time, while those that overspend on high-priced free agents or fail to adequately address key positions are likely to struggle.
