Unfortunately I found the way to score easily in this game, which is too bad as I hate the cheap goals.
To try this, go to Free4All. Pick Jarome Iginla of course
Now start on the right side of the rink level with the top of the circle. Skate in diagonally towards the bottom of the left circle. As you approach the slot, hold down the slap shot button. Jarome will continue to drift towards the left side of the rink. Aim for the top left corner, and release the shot button just as the puck is getting close to the left circle.
After trying it out for a bit it seems like about 9 of 10 go in
I guess the good news is you will get hammered alot trying this during the game, but breakaways will forever be ruined.
