If you’re a fan of the Nashville Predators, you’ve probably been wondering if Mike Fisher can return from retirement and still be as effective as he was last season. Maybe you wonder if he’ll take minutes from a younger player with more to offer at this point, whether it be Colton Sissons, Austin Watson, Calle Jarnkrok now or Eeli Tolvanen later. One cannot help but wonder if Peter Laviolette will tire of being asked if Fisher is in or out of the lineup once the playoffs kick into gear. Friday won’t answer those questions, although we’ll at least get a look at Fisher as he makes his 2017-18 debut for the Predators, who close out a back-to-back set. They rallied from down two goals to beat the Edmonton Oilers 4-2 last night, and they turn around to face the Vancouver Canucks tonight. Really, back-to-backs rank as no-brainer situations for Fisher. Going further, maybe you rest the veteran one night, then give someone a break by lining him up the other? There’s also the unfortunately real possibility that injuries could always silence the debate, whether it be Fisher getting hurt or the attrition of the postseason limiting Laviolette’s options. Still, at the moment, it’s not that easy to decide who to bump from the lineup for the veteran forward. Especially if he must be at center in any situation.
