It's more how I would value Cernak, the asset, to us right now.
Cernak is a fine player. I'd love to have Cernak. However, he wouldn't make us that much better right now, because all he can do is help reduce (slightly) our being caved in, and cannot help us do anything else. He is also not cheap, is signed for a long time, and is too old - no player above the age of 25 is likely to be both effective and on the next good Sharks team. What we need are more lottery tickets to acquire younger players who might be part of that team.
Cernak is a fine player. Cernak is not a fine asset. Cernak is also an asset whose cost to acquire far outstrips his utility to a team in our position - I would consider literally any price paid for Cernak to be too much (yes, obviously we'd have to send something cheap back - give them a garbage prospect like Wiesblatt and/or a 6th or something).
However, that won't happen, because Tampa has nothing I would consider we could possibly want as a sweetener.
