<p>NESCAC is mostly Division 3 athletics whereas Ivy is Div 1 athletics, meaning they don't compete head to head in many sports (or at least none that I know of). Some NESCAC colleges have great sports programs like Williams which wins that Sears/NACDA Cup (<a href="http://nacda.collegesports.com/directorscup/nacda-directorscup-current-scoring.html%5B/url%5D">http://nacda.collegesports.com/directorscup/nacda-directorscup-current-scoring.html</a>) just about every year (for Div 3) and Middlebury. Hard to say though how they compare to Ivies.</p>
