I heard that same thing about Karlsson and I think he would take a bit less to play with his buddy in Tampa on a contending team in a state that has a tax advantage.
I think it might take a bit more to move Callahan but not much and you might get a bit less for Johnson but you're pretty close all in all. I also think Point might want a bit more then $8 but not much more.

Massive overpay for Tampa to move one year of Callahan. No way.

- The Callahan one got me thinking. If we trade away Raddysh with Callahan, both Yzerman and BriseBois will know that he's a great prospect that is in our top 5 propsect in the pipeline. And both Yzerman and BriseBois know that the season after this one, he'll be a NHL player. That's why BriseBois will ask a late pick back (at the very least) as both GMs know the prospect very well and both know he'll be a good NHL player.
But that's my thought process haha, maybe I'm completely off.

- For Pointer I took the Evolving Hockey prediction for a 5 years contract (8.2M) and took away a million dollar total, over the 5 years, as little discount. An acceptable discount if you think about potential of the team, chances of keeping the core together during next offseason and the chance of getting EK65 on the team.
As Stamkos said: “Part of the culture that we have here in Tampa is kind of that team-first mentality, and if you want to keep a good team together, guys are going to have to make little sacrifices along the way,” Stamkos said. “Whether that’s in terms of money or term or ice time or role on the team.

“That was something that — it’s kind of non-negotiable on this team, in terms of doing whatever it takes to help us keep the core together and keep being a productive team. That message was pretty loud and clear early when Steve got here and established himself as a GM, and continued to be that way.”

- And Johnson, I don't know. I feel like general opinions are contraddicting on him: some would pay a decent amount (as he is cost controlled, long term and may have a chance to step things up with a change of scenery) and others would pass on him. I tried to reach some kind of middle ground haha

Yeah, as I just wrote I'm kinda torn: knowing Yzerman, he'd try to get a prospect out of it, but if that's the case a pick will have to go the other way. What pick is now the question

Katchouk and Cally for a 4th at best but if Tampa has to throw in a prospect they might as well just keep Cally for a year.

Maybe I'm undervaluing Raddysh a bit so it probably is fair then.

Yeah Tampa has done well to build a certain team culture there and guys want to play on winning teams but I think Point will be just a bit more then $8M.

I think Johnson's value will be determined by if some team thinks he can be a 2nd line center or not though his contract seems like decent value either way.

Gourde I'm really not sure about, wonder if he's just a product of playing on a stacked Tampa team and if other GM'S are thinking the same.

Callahan's contract is easy to deal with even a buyout is cheap and that's why every team has done a mock where they take Callahan in exchange for some assets. Now if Tampa only wants to give up a 4th and no prospects for taking him, it's more than likely that he stays in Tampa next season. Tampa not wanting to give up more than a 4th is in the realm of reasonable and not unfair but I wouldn't take Callahan for only a 4th it's too much hassle for it.

if I am either Karlsson or Point my contract has a nmc so I don't screwed if the Bolts want to trade me. This could be a problem when the Seattle draft happens

Point cannot have a NTC/NMC as he's under 26 y/o. He'll have a NMC once he gets there with his contract (just like Matthews). EK would very likely have a NMC that becomes a M-NTC in the last 2 years of his contract.

I would not see it as a problem, as these 2 players would be 110% protected no matter what at the expansion draft

I certainly do hope the price would be around what you say, but probably teams will want some more, also because Callahan leaving is crucial for Point/going after a UFA and other GMs know that

Yes on Johnson and Gourde deals .. 2nd rounders fine for them to me .. HUGE no on Erik "Damaged Goods" Karlasson and agree with above that no more than 4th for Callhan straight up or else you just keep him

The argument on EK is meh: as Lightning’s Fox Sports Sun analyst Brian Engblom once said, “Erik Karlsson at 85 percent is probably better than 99 percent of the players at 100 percent. His anticipation, his hockey sense, is off the charts. It’s as good as anybody, Sidney Crosby, I don’t care who. He used to not care enough about defense but I think that’s gone.”

The guy in the 5 seasons prior to this one has missed a total of 16 games.
He is injuried, he'll heal. If Bouwmeester was able to fully recover from a ankle surgery, so would Erik mofo Karlsson. And he's 28, not 34.
And think about the playoffs, a puck carrying Dman like him would be perfect to contrast the trap game if the opposing team tries to do that to us.

If we have a chance to get the best Dman of his generation, with THAT AAV!!!, you don't even have to think about it twice.
