Boston Celtics vs Orlando Magic, NBA

Every team gets an attack and a defence rating from its results this season and last, with recent games counting most, plus a home-court edge. Those give the projected score; the expected margin and how much scores usually swing around it give the chance to win. When bookmakers have priced the game we blend in their odds, which also reflect injuries and rest. The prediction is locked at tip-off, and the season record above counts only those locked picks.
