Filppula is a 3C at this point of his career.
His possession metrics are meh, his E +/- has declined the last 3 years.
His scoring has bounced back from last year, he's basically a 10-20 30 guy at ES. He's scoring at 1.83 pp60 at ES but was 1.03 and 1.40 the last two seasons, so expect some regression to the mean next year.
He's basically the veteran C people wanted to pick up as a stopgap on a 2 yr $6-7M contract, a little more expensive but only one year, to buy time for Vorobyov and Rubtsov to grow up, and to see if Laughton can handle the job.
