For as intriguing a goalie prospect as Blomqvist is, I doubt the Kraken will be too willing to subtract from their roster during a period when their contention window is just starting to open. Tolvanen has become a key cog in the Kraken's balanced attack. I think Seattle declines this trade offer and just hangs onto Tolvy.

Tatar on short money could work as a Guentzel stand in

Guentzel is only out up to 12 weeks, Which means he's probably only out for the first Month of the season. Probably due back by Mid-November.

It’s “at least” 12 weeks, not “only”. Also ankle injuries are common for setbacks so they should take their time brining him back

Yeah that's true, I've seen ankle injuries with Detroit players being much longer than just 12 weeks. Some were as long as 4 to 5 months depending on the severity of the injury.
