Until recently, I felt the result was pretty random when going for the wrap around. However, as everything else in NHL 09 it's about timing and patience.

For those of you not familiar with wrap arounds, let me quote Below:

"If you shoot when your player is coming around behind the post, your player will automatically go into an animation where he stretches out and tries to wrap the puck right inside the post. Your success is determined by when you time your shot, your angle coming around the back of the goal, and the goalies position." - nhl09perfectionist.blogspot.com

With that said my opinion is that the goalie's position is the key factor. I will illustrate this with a clip where I circle around behind net until I find the right opening.

Of course sometimes the opening is there right from the start:

The boards are useful for puck transportation both in defence and offense.

Instead of dumping the puck, a slapshot via the boards is a very good way to get the puck out of the zone, and as a bonus you won't risk putting the puck over the glass when on PK.

When attacking, using the boards is a snekay and pretty safe way to get passes through to a player behind the net. Also (and this is pretty obvious), if it looks like you're going to get body checked, shoot or pass the puck along the boards to avoid a counter attack.

Theory, being a left shooter coming from the right:

1) Pull the RS to the right
2) Bring the RS back a little
3) Hold L1 (LB X360)
4) Move LS to the left
5) Move the RS to the left (this will send the puck to the left)

Once you hit and hold the L1 button the RS controlls where the puck will go and the LS where the player goes, so there's a lot of fun to be had with L1-dekes.

I play D in BAP and I've allways had a bit of a problem with the camera. I used to play with it High (behind me) but if I, for example, was skating up the left wing, I couldn't see if a team mate was open to the right of me.
So I tried to play with the camera in classic mode but when the puck was in the offensive zone, I couldn't see if an opposing player was behind me waiting at the red line (a big problem in online team matches).
However, I found there is a solution to the problem. You can swith, during matches, between locking the camera to the action or to your player. This is done with the SELECT button on the PS3 and the Back button on the 360. So if the puck is in the offensive zone and you lock the camera to your player; you will no longer see the puck if you skate back and enter the defensive zone (but a red marker representing the horizontal position of the puck handler); lock the camera to the action and you won't see your player (but a red marker representing you).
I usually switch to player lock when defending (or trailing an opponent) and to action lock when attacking.

The camera lock only works in BAP-mode and it doesn't work when you set the camera to High or Low.
