Everything is centralized around Baltimore. Often the committee members have deep ties to people there or are the people. The HOF is based there as is US lacrosse. All of the acc teams outside of Syracuse have very close ties to the area due to current or past coaches and the fact they recruit they area extensively and have for decades.
Make no mistake, there are often people on that committee who are friends with the coaches of teams they are evaluating.
Rutgers and the B1G in general need to do a better job of infiltrating the power structures of lacrosse, and obviously the tournament committee itself.
Take the chair of the committee itself. Towson St AD. You think the bias potential exists for say, Loyola? I can tell you Richie Meade in the past had an obvious bias. He was a catalyst in Rutgers not getting in the year we beat Hopkins twice and made the B1G tourney finals.
