Replacing who? Its not like trying him on the wing is gonna make him forget how to play center. Bjork and Kuhlman are the clear weak spots on this roster and it would be good to see if Studnicka can handle it if we need him in the playoffs.
I've said before that I envisage Studnicka at 4C next season and I still believe that may well turn out to be the case. A one-year apprenticeship on the 4th line prior to moving up to replace Krejci in 2021/22 on the 2nd or follow Coyle up the chain if they decide to go that way. Kuraly can play wing as he's been doing lately anyway and Lindy will remain the reserve center. It's been clear for awhile that management are taking the long road with Stud and his time has not yet come. I expect he may get a game or two in Boston at the start of April if we have the luxury to rest a few guys before the playoffs begin, but that will be all for this year.
As for Bjork he's just going to have to work a little harder and prove he has it in him to lift his game to playoff-level intensity. He and Kuhlman are battling for one spot and that's no bad thing. Karson may not be the most skilled guy in the world but he's not shy about getting his nose dirty and being relentless on the puck, and he's already proven he can play postseason hockey, at least in short bursts. Bjork may have that little bit of extra talent but that won't count for much if he can't put it to good use on the ice. He's already come a long way this season but this is probably the next big test for him.
