I think the Shox just weren't well prepared to play against William and Mary. That's on the coaches. Also the Princeton style offense has always caused Gregg Marshall teams a lot of headaches (see Air Force last year). With the new rule changes and so many fouls called as players drive to the basket this year it is probably a great offense to run. Hard to defend that effectively this year.
I'm not too worried yet. Still some work to do, but you can say that about everyone this time of year.
It says a lot about this teams potential when the coaches and fans are upset with a 17pt win.
