When the Caribou High School boys basketball team captured the 2020 Class B state championship on a buzzer-beating shot in double overtime, its opponent left the court crestfallen. “It was probably as heartbreaking as you can get,” said Travis Magnusson, head coach at Maranacook Community School in Readfield, which fell to Caribou 73-71 at the Cross Insurance Center in Bangor. The Black Bears were expected to be among the favorites to win the gold ball this winter, spurred by a pep talk immediately after last year’s state final from senior captain Skyler Boucher. “Everybody’s in the locker room and it’s really emotional, and one of our seniors gave one of the best speeches I’ve ever heard anyone give,” Magnusson said.
