On Sunday the NBA Double System Play is on Boston. Game 701 at 6:05 eastern. Boston fits a solid system that plays on rested road dogs of 5 or more that are off a home favored loss at -4 or less and scored 90 or more points, vs an opponent like Detroit that scored 100 or more as a road dog. The Pistons battled back before losing 111-108 in Memphis on Friday. That overtime loss sets them up in a negative system that plays against home favorites with 1 day of rest at -5 or more vs an opponent off a loss, as long as the home teams played just one overtime. These home favorites are 5-24 to the spread since 1995 and this system has won 6 of 7 times the last 6 years. Look for Boston to hang in and get the cash. Take Boston plus the points.
