What is a key impact of rookie contract rules on team cap planning?

The key impact of rookie contract rules on team cap planning is that contracts must adhere to specific structures and limitations, including provisions like the 25% rule. This rule allows for only a certain percentage increase in salary from one year to the next for rookie contracts, which helps teams manage their salary cap more effectively. By having these regulations in place, teams are compelled to plan carefully around the restrictions of rookie contracts, ensuring that they remain competitive while also complying with the overall constraints of the salary cap. This structured approach forces teams to make calculated decisions when bringing new talent into the organization, thus affecting their overall budget and strategic planning for the roster.
