Mike Hoffman has filed for salary arbitration. Hoffman led the Senators last season with 27 goals scored, though his perceived defensive shortcomings got him demoted to the fourth line toward the end of the season. The two sides will continue to negotiate, as they can come to an agreement any time before the arbitrator's award. As a famous example, last year P.K. Subban had his arbitration hearing with the Canadiens, then signed an eight-year, $9-million deal before the arbitrator's ruling was released.
