NHL 10

You must score 25 goals with your Be A Pro Character.

I had my Be A Pro Player under a few saves as I tried different positions and different character types, and even though it added up to 25 goals between them, it didn't pop the achievement, so it has to be one save. I am assuming this can be over multiple seasons, as long as it is the same character/save.

It would be easiest to start a new season on Rookie, and select sniper forward as your character type. If you aren't good on faceoffs, be a winger. Change the shot to auto aim, and no line changes. If you have any bonus equipment put it on the player. With no line changes, your character will always be on the ice(unless penalized) and won't get tired. I personally find it easier to score on powerplays and pk, so I kept penalties on.

Right Trigger calls for the puck, so stay near the blue line when the puck is in your zone covering the point man. I found going in on off wing, wiggle the right stick and then do a quick slap shot from the slot worked well. By off wing, I mean if your player shoots right handed, then come in from the left, or vice versa for left handed shots. I scored 10 goals with my player on rookie in one game doing this with whatever length of period is the default. Essentially, anywhere from the slot is the easiest to score from.

If your game is close, they will pull the goalie with 1 or 2 goals down, so make sure you call for the puck and lug it up when that is the case, then shoot when your character is half way between the blue line and the net with a wrist shot.

The achievement unlocks after the game once it saves.

not sure if this works yet but this method worked for ALL STAR achievement and GRADE A. I will update it when im done.
just go to nhl Be A Pro, choose crosby. Turn line changes off before the games start and put it on rookie. When the game starts turn all your attributes up and the CPU's way down(pass speed, shot power)
and I only played one game so far but i got 8 goals and 5 assists so it wont take long to get 25.

CONFIRMED** this works with NHL BE A PRO and i got this in 5 games.
i have 5 games played, 27 goals, 15 assists, 42 points. with 5 minute periods

as simply as it's said: score 25 goals with your be a pro! if you into this game shouldn't be a problem.

otherwise create a winger be a pro character
sniper / power forward
spend xp points on wrist shot accuracy or power
choose the lowest difficulty setting
if you want to set the periods lenght to the max, so you haven't to play too many games
play egoistic, don't take care of overall ratings, use your teammates if they're in puck posession press the pass button, so they try to feed you
if your line is on the bench, press the line change button, so you can return quickly on the ice, but if you're too tired, you may not score in high fashion

Has to be done in Be A Pro!!If you want to get this achievement the easy way, just put the difficulty level on Rookie.
