Gone are the hockey-like line changes. So, too, are extended minutes on the court for most of the non-starters on the Camden boys basketball team which has gone to a more traditional substitution pattern under interim head coach Ron McKie Jr. What has not changed, unfortunately, are struggles on both ends of the floor. Put in a quick 12-0 hole in the first three minutes of play, the Bulldogs dropped their fifth straight game in a 60-48 defeat at the hands of visiting Richland Northeast in Friday’s Region 4-AAA contest played on the Michael G. Culp Court.
