The PCB had shifted the PSL window with a view to improve the quality and availability of overseas players whom the league would be able to sign. When the PSL was in the February-March window, it also had to compete with the SA20, ILT20 and the BPL for players. ESPNcricinfo had reported last year when the window was changed that holding the PSL draft after the IPL auction had also been discussed, to have greater clarity about the availability of overseas players for the league. Leading into this season, the IPL auction was held in November 2024 and the PSL draft in January 2025.
