Easier scoring:
To get a goal easier, do a wrap round. Go to the other side of the goalie and 
shoot. Note: This does not always work. 

Easier rewards:
To unlock more rewards on a higher difficulty level, go to "General Options" and 
choose the desired difficulty. Then, go to "Advanced Options" and turn down the 
CPU skills while turning up the human skills.

Easier wins:
Go into "Roster Manager", and "Trade Players". For example, if you want the New 
Jersey Devils to win frequently, select their team, press Y, then cycle through the 
teams. Look for very good players (90+ overall) and select a couple of them. 
Trade them for players on the Devils such as Gionta or Stevenson, who are not 
very good. Even if you trade a 70 overall person for a 90+ person, the CPU will 
accept. When you are done, go back to the "Roster Manager" screen, 
select "Player Status", select the Devils, and scroll down the player names. Dress 
the players so they can play. Then, return to the roster manager screen once 
again. Go into "Edit Lines", change the lines, and put your players from the other 
teams into lines.

All tasks completed:
Press R(2), L, Left(2), Down, Y, R, Y, L, Up, Right, Y, Down, Left(2), Y, R, Down, Up 
at the game modes screen. Exit that screen then enter the cheat menu from the 
main menu. All tasks should now be marked as completed. All cheats can now 
unlocked individually by selecting them. After doing so, you can go to the team 
selection screen to choose any previously locked team, select the previously 
locked jerseys, and play the air hockey, mini rink, pond hockey, and speed 
hockey mini-games.

Players never retire:
Change the age of your players by going to "Edit Player" in a franchise. You can 
make them younger so they never retire.
