NHL 2K7 - Platform: Playstation 3

Easy goals:
-----------
Hold Speedburst while on a break away then hold Square for a slap 
shot. Always take the shot at an angle. You will score about 95% of 
the time.

Cheaper players:
----------------
Get all the best players on a team. Make a franchise and play. Near 
the end of the year (season or playoffs) make all your players bad 
and sign them. You will be able to get them for cheap.

Avoiding bad phone calls:
-------------------------
To avoid bad phone calls just save the game and answer the call. If 
it is a bad call, reload the game and try again.
