There are several movement drills that help with angles and positioning. These classics help you ingrain your movement into an automatic response rather than needing conscious thought.
Also, a large portion of your on ice movment is going to be using a shuffle to follow the puck position. HAving a consistant shuffle distance is key. With varied shuffle distances you can end up off angle very easily. To test yourself try this little drill....
Set up on the blue line on the defensive side. W ith eyes closed and left skate on the defensive edge of the blue line take two shuffles to the right, three to the left and one back to the right. IF your shuffle distances are consistant you should look down and find yourself back in your same start position. IF not you need to work on this aspect.
The crease shuffle is a great tool to develope your shuffle. I am a firm believer in the Popa goaltending horseshoe method which has the crease diveded into 9 points of coverage.
Which ever you choose to do, make sure that you shuffle the arc consistantly. From the left to the right post and back the other way, it should be an EXACT same number of shuffles.
These next "classic" drills will help you gain hte consistancy that will solve your problem. Also, there is nothing wrong with waiting at the bottom of the crease center of your net and moveing out from there. Some say that reaching back and hitting the post with your stick can be a guide. I dont encourage this nonsence. I realize that every rink is not the same but once you have your skating down, use those visuals in front of you to develope a "net radar" for where it is behind you. Sounds kind of flakey but over time it will come. Be confident, work on your skating skills and it will fall into place. Perform these drills at a pace that has you doing so PROPERLY. work speed into the drill as you can. Correct performance is more important in ANY drill over simple speed.
To find your MAX distance start in post coverage. take TWO HARD STRIDES towards top center of the crease, stopping with the same skate you drove off the post with. Dont know your age or hight but it should put you between a foot(younger) to just about halfway to the hash marks(mature). Try to keep inside this max positional range while you develope your skills.
