He is set on moving Fiala like he is set on never moving Dumba. If there was a way to keep 22, but it involved moving 24....he wouldn't take it, because he seems set in his ways.
I just don't see him as set on never moving Dumba.
Trade Fiala and keep Dumba, or keep Fiala and trade Dumba. Losing either of them hurts the team equally and the W/L record at the end of next year would be within a couple standings points. Fiala will be a bigger cap hit than Dumba. Fiala also gets a better return in trade than Dumba. From the business side of things it's an easy decision to make.
The only real difference in who is traded is the secondary entertainment value for the fans. That secondary entertainment value for the fans doesn't matter for the business side of things. Fiala, Dumba, everyone on the team not named Kaprizov are just sideshows, not the main attraction. The fans will show up, tune in, and buy merchandise because they want to see the main attraction: dedicated fans of the team and/or to see Kaprizov.
Kaprizov is the reason Fiala will be gone. Fiala would be the headliner if Kaprizov wasn't here. Kaprizov is already getting the money that Fiala would have been paid.
I get why GMBG doesn't want to respond to questions about this when I look at it from his perspective. It's like he's the burned out single parent of a toddler (media/fans) asking how does the car start. You can explain to them the inner workings of an internal combustion engine, how the fuel system, ignition system, timing, and electronics systems are all connected when the key is turned. They won't understand any of that. So the answer is "put the key in this spot, turn it, and car goes vroom."
