NHL 2K10

Here's an obligatory turbo controller solution if you have one. You'll need two controllers plugged in for it, so another wired controller or a Play and Charge kit is needed. As usual, this is one minute period quick games, set to rookie difficulty and icing, offsides and penalties off.

Player 1 (sign in as this one) should be a particularly good team or a created team with superstars, Player 2 should be Team Denmark or Team France. When the game starts, pause from both controllers and set the position lock to Goalie.

Player 1: Turbo controller. Left analog stick is rubber banded down, and the button is turboed.
Player 2: Wired controller. Left and right analog sticks are rubber banded together.

Player 1's goalie will skate down but still be somewhat functional. Player 2's goalie will flop out to the side and leave the net open. Since your goal is somewhat protected and you have the better team, you'll win much more than your opponent. The turbo controller will override the wired controller and auto-rematch when the game is over.

While letting it run overnight for about 10-12 hours, I got roughly 100 wins to 6 losses, as well as 600 goals and 700 assists.

This is a definite grinding achievement. To start off, go into Options>Difficulty and turn all the CPU sliders way down. Then go into NHL Rules and turn the period lengths to 1:00, and icing and offsides off, as they'll only slow the game down. Likewise, after you get your PIM/ppg achievements, turn penalties off as well. If you want, create a team with all the worst players from Free Agency has to offer, and then edit the goalies to be about 30s or so. Even at 3 minutes of game play, you should rack up the goals pretty quickly. After you get all the scoring/points achievements, simply score once in each game and play keep away until the final buzzer. There's no point in racking up the extra goals, and it'll save you a lot of time.
