There were no men’s rugby games here this fall, for the first time in a very long time, though Kevin Bunce, who’s been overseeing Section XI Warriors youth sides that have on them players from East Islip, Babylon, Mount Sinai, Shoreham, and the North Fork, as well as from Sag Harbor and East Hampton, is pretty sure that men’s rugby — though probably no longer strictly under the Montauk Rugby Club’s aegis — will live again in the form of a countywide powerhouse.
