Jim,
Were you sure to test IE7? I'm running that, and when I first hover over the "Games" link, it gives me a javascript error, then on second hover it will pop up the menu, but it will disappear in a short time unless I click on one of first couple links. Anything further down the list takes too long to get to before the menu disappears. (This only happens with the Games menu, none of the others in the hockey section. I didn't try the football section).
Also, I would suggest doing something different for those menus, visually. Some of the links (Merchandise, Photos) are actually links, while others can not be clicked on because they are menus. Not very intuitive unless you know what is a link and what isn't.
Just a couple suggestions.
