Unlock your character without spending any points:
In season mode, go to the unlockables section and unlock the player you wish to use. When leaving the screen, do not save the Gretzky Challenge Data. Then, draft the player you unlocked to the team of your choice and save your season. Then, go back to the Gretzky challenge section and load up your old Gretzkey Challenge stats (or you can just reboot the PSP). You will have your points back, and the player you unlocked will still be shown as locked. However, he will still be on your team roster.
