Change team jersey:
Hold the X + Circle + L2 buttons when the "Just a Minute" sign appear 
on the screen. Keep those buttons held until several seconds after 
the sound of a puck is played, to see the teams in different outfit.

Change one game series to seven series:
Start a seven game playoff before the end of the season. The 
"continue playoff" option will be accessible. Now when the season 
ends, it will automatically overwrite the old playoff, but retain 
the seven game format. Submitted by Tomatoguy
