I do not agree on Gushchin having a real chance. You don't put a player whose best attributes are offensive on the 4th line. They put him in a position to fail, and he failed. Look at how much Will Smith struggles playing on the 3rd and 4th liners. Obviously Gushchin is not on the same level as Celebrini, so thinking he's going to succeed in that situation shows a total lack of ability to accurately evaluate your own players. However, I do agree that his career on the Sharks is probably over.
I honestly think they should waive (if they can't trade) Grundstrom, Dellandrea, Kostin, Rutta and Goodrow and call up Mukhamadullin, Bystedt, Bordeleau, Gushchin and Cardwell. Pray that someone pops.
