You may want to add some production elements – I recently got some very nice stuff (for a really good price) from Digital Juice – They have animated backgrounds (called Jump Backs), wipes, video clip-art elements (called Motion Design Elements), overlays, etc… that could really spice up your work.
They sell certain pieces seperately (Jump Backs, Motion Design Elements) and also bundle coordinated sets together in their Editor’s Toolkits (they have one for sports and it does include hockey).
You could also add some interesting titling using something like Bluff Titler – It’s helped me with some of my stuff.
