- Another name that has emerged as a deadline candidate is Niko Mikkola of the St. Louis Blues, according to Seravalli, who profiled his case yesterday. Mikkola is a pending UFA who could offer physical, shutdown play in a depth role for a contender this season. Given his age – the big Finn won’t turn 27 until April – he could also be a candidate for an extension with whatever team acquires him, should the Blues decide to sell.
