How many years does a designated rookie scale player extension add to a player's rookie scale contract?

A designated rookie scale player extension adds 5 years to a player's rookie scale contract. This extension allows teams to retain a promising player who has shown a high level of performance during their initial years in the league. The designated rookie extension is a critical option for teams looking to secure young talent for an extended period without entering free agency.

In the context of the NBA's salary cap and contract rules, this mechanism provides a significant advantage by allowing franchises to extend their control over a player who has proven to be an integral part of their roster. By adding 5 years, teams can plan their rosters more effectively around their core players, while also ensuring that they have sufficient cap space to build around them. The rules surrounding these extensions are designed to foster competitive balance by allowing teams with drafted talent to keep their stars, thereby promoting the development of homegrown players.
