Jack Eichel is staying put in Buffalo for a long, long time. The Sabres announced on Tuesday evening that they have agreed to terms with their star forward on an eight-year contract extension with an average annual value of $10 million. The deal will be officially signed on Wednesday, reports TSN Hockey Insider Pierre LeBrun. Eichel is entering the third and final season of his entry-level contract that carries a cap hit of $925,000. Performance bonuses could push the total value of the season to $3.775 million. In 61 games for the Sabres last season after missing time with an ankle injury, Eichel had 24 goals and 33 assists. He slightly out-performed his rookie campaign of 24 goals and 32 assists in 81 games. This season, the Sabres are expecting him to take an even bigger step forward.
