What does cap space roll-over allow teams to do?

Cap space roll-over is a mechanism that allows teams in professional sports leagues to carry over any unused salary cap space from one season to the next. This means that if a team has not utilized all of its available salary cap, that unspent portion can be added to the cap for the following season. This roll-over capability can provide teams with greater financial flexibility in the future, enabling them to sign additional players or negotiate contracts with a higher degree of available funding.

This option reflects a strategic approach to managing a team's financial resources over multiple years, ensuring that they can maximize their spending power when opportunities arise, such as during free agency or in contract negotiations. The other choices do not accurately capture the essence or purpose of cap space roll-over, as they address different aspects of team financial management or limitations set by the salary cap rules.
