Bob Shillinglaw knows that by announcing his plan Thursday to step down at the end of his 39th year as head coach at Delaware and 42nd overall, he would provoke a certain amount of hoopla and nostalgia. But he prefers that his retirement not be a distraction. "One thing I try to make very clear is that this is their experience, their year," the Severna Park native and graduate, who lives in Elkton, said Friday morning. "It shouldn't be about me; it should be about them." Shillinglaw, 64, has coached the most games in NCAA history. His career record with the Blue Hens is 303-295 and features 15 conference titles and four trips to the NCAA tournament between 2005 and 2011, including a run to the Final Four in 2007. Delaware has stumbled in the past five years, however, going 28-48 and qualifying for just one appearance in the Colonial Athletic Association tournament.
