Was wondering the same thing and came across this on the devils site: https://www.nhl.com/devils/tickets/playoff-tickets
No date yet but, there is a pricing structure for members and general public that is more reasonable than those $300 listings.
Tanner Jeannot could be a cheaper Tom Wilson to consider if Nashville becomes a seller. Hasn't matched his 24 goals from last year but is still cheap and an RFA. Would be an upgrade over anyone on our 4th line
