How to unlock the Blueline Tally achievement in NHL 2K8 - Definitive Guide
Turn the sliders to 100 for you and down to 0 for the CPU. Play as Anaheim and put pronger and niedermayer on the 1st Defensive pairing. Let one of them carry the puck and try the wrap around and backhand deke methods of scoring. With the sliders in your favor it will only be a matter of time before you score.
This can be a bit difficult but shouldn't take much. Best way, play an All-Star Team against Denmark or some really low-rated team. Set your periods to 5 minutes, Real-time clock. Get two of your players to take penalties (this will help open the ice more) and score with your defenseman. If you use this method, you will also unlock "Can't Keep Me Down."
