Jake McKinnon picked up the puck in his own zone and glided around three Weymouth defenders before creating and finishing an eye-opening breakaway goal at Connell Memorial Rink Saturday night, leaving spectators on the glass to gasp: Wow. He let out a quick fist-pump before being swarmed by his teammates at Framingham High, but as he enters his fourth season on the varsity, his skills are not a surprise to the Flyers. Paul Spear, in his 13th season as coach at Framingham, predicts McKinnon will be the best player in the Bay State Conference this season, citing his enormous talent, along with those intangibles that are often unquantifiable.
