There is a fair amount of analysis (decent in the official posts and ranging from very astute to very silly in the comments) on the Inside Lacrosse website,
www.insidelacrosse.com, if you want to get a better feel for some of the issues. In the broadest possible terms, Duke likes to pay an uptempo game with a lot of running and looks for opportunities to score in transition when they can. We are also very solid on defense except at goalie, where we have a freshman who probably didn't expect to be the starter this season (the likely starter was dismissed from the team at the beginning of the season for unacceptable conduct of some kind) and seems to get a bit overwhelmed at times. Notre Dame likes a slower paced, half-field game. They are careful on offense--working to extend possessions and take quality shots--and extremely strong on defense. They focus especially on trying to shut down transition scoring, both by collapsing on defense and by working hard to avoid the kinds of mistakes than can start fast break situations in the first place, and their goalie is both huge (at 6'4", 254 lbs., he covers a lot more of the goal than most goalies) and playing extremely well right now. It's an intriguing match up and it's not at all obvious who will win, or even who "should" win, though if we can win face offs, avoid sloppy mistakes on clearing (like the ones we made Saturday) and find ways to score on their goalie, I think our chances are pretty good. Those are big ifs, though.
