Own the creaseG 15

An easy way to get this one done; start up a quick game with whatever settings. Rookie and 3 minute periods if you want to get it done quickly. You can also use an NHL all star team against a junior team if you want. Play normally (not as the goalie) until just before the end of the game, making sure to get the lead and not give up a goal. Just before the game ends, go to settings/select sides, and position lock yourself as the goalie (click left or right stick until G appears beside your icon). Now return to the game as the goalie and let the clock finish running out...achievement unlocked.
