Olofsson? Nylander? I would prefer to see Olofsson, not Dzingel, and take Nylander instead of Sheary, Girgensons or Okposo, you can not bury them again in AHL.

No need to pay dzingel for his outlier year when you have olofsson. Look for sheary to have a bounce back year. If he shoots at his career shooting percentage he has 18 goals last year

Sure, that works as well. I think Olofsson is ready, and I could bring him up later in the year. But as you indicate if I trade away or not sign Larsson and Girgensons, it opens up about $2,000,000 more cap space.
Okposo on the other hand is a conundrum (riddle, wrapped in a mystery, inside an enigma), he is paid as a top line forward, but produces as a 3rd line forward. I am so tempted to put him on the top line with Jack and Jeff and see if he could get 20 or more goals and 50 or more pts. IMO he may become a LTIR if he suffers one more concussion.
If Reinhart is on the second line, with Dzingel and Strome, and they all produces as well as they did last year , they would give us over 60 goals.

You are most likely correct about Dzingel, Sheary and Olofsson.
I could be in error, but I think Sheary was to be Jack's LW until Skinner became a Sabre.
I know I am over paying for both Dzingel and Donskoi. If Dzingel can give the Sabre's his average goals and pts per 82 games we would get 20 goals and 42 pts, not enough for $5,500,000 but better than any other 2nd line LW we have and it would not cost any Buffalo assets, Donskoi may be better suited to the third or even fourth line as his career average is only 13 goals and 35 pts. I am hoping the Strome has finally found his game his career goal and assist avg is 15 and 38 and last year he had 19 goals.

That second line is prime to disappoint

I guess you are correct, among them they have 109 goals the last 2 season combined, so that averages 55, not bad for a second line. How many goals did Buffalo 2nd line have last year? Let's presume that would be Sheary, Rodrigues and Pominville 39. And the previous year? O'Reilly, Okposo and Pominville (you know it was not that because Okposo and Pominville are both RW) 55. Now how much did Buffalo have to give up for 55 goals? A second and sixth, but got a third in return. So let's not take averages, how many goals did Donskoi, Dzingel and Strome have the previous years? That is 59 in 2018-19 and 50 in 2017-18. BTW what did it cost to add 50 goals, nearly nothing. I will risk the disappointment.

Lets pretend that goals they got in the previous 2 seasons has any bearing on future performance and how those players would pair and work together within Buffalo's system. Strome for example was completely disappointing on 2 seperate teams before landing in NY. Seeing as hes the lynchpin of the line and has 37 As in the last 163 games we could compare Dzingel and Donskoi's centermen that led them to 26 and 14 goals this year and 23 and 14 last year respectively. Donskoi had Hertl (63A in 156) and Pavelski (70 A in 157). Dzingel had Duchene (71 A in 155) mostly but also with Tierney Dubois and Turris for parts of the last 2 years. Not to mention Strome has played RW for most of the last 2 seasons, with RNH Draisaitl then in NYR with Namestnikov Fast and Chytil. I like Donskoi and Dzingel, both are going to get more so Buffalo is going to have to out bid other teams, both could be regrettable contracts down the line. Strome found a nice fit in NYR but their is nothing saying that he will mesh well in Buffalo or even if he'll have a similar year next year. Therefore that line is prime to disappoint

sure, who do you have in mind for #2 center next year?

Mittelstadt

That is because he played so well last year?

Were again pretending last years stats have any bearing on future production.

There you go again, pretending you know everything there is to know.
If past stats cannot be used to predict future performance, tell me what can be used.
While you offer excellent reasons for Donskoi, Dzingel and Strome to fail, there is ample evidence that they will not.
While Buffalo has an excellent top line, it is far away from being a playoff team that adding nearly free talent is the only way to make the team respectable while the home grown talent has an opportunity to develop in the minors.
In hindsight Thompson, Mittelstadt and Pilut should have spent most of the season in Rochester. Every once in a while they would display flashes of why they were highly touted. Spend more time in Rochester to make those flashed more consistent.

Oh cause Mittelstadt showed 0 improvement, I forgot rookies cant mature anymore. I have 0 intrest in piling on a ton of FA contracts just to force a playoff run this season, especially after all the organizational changes. Okposo is example A

Fine that is great and it is your opinion. These changes are cheap and not long range as Okposo. Maybe we pay less and less term, but they are a move forward. If Olofsson, Nylander et al progress the players signed can play a lower line and the Sabres still have more talent.

The Sabres can not pay less on any free agents and these guys will have multiple teams after them. Buffalo will have to pay more, Donskoi at least 4 could get up to 4.75-5, and Dzingel would be over 6

You are correct, there will be other teams bidding on them. If Buffalo could move out Scandella, they will have more cap space than nearly any other NHL teams. If they can focus on getting 2 or even 3 UFA's, they will still have ample space. While you are correct about the upper limit for Donskoi and Dzingel, I used this as a starting point:
https://docs.google.com/spreadsheets/d/15E1qqh3OfHvvhbv_pICfKT7VR1jJEVhWQOyKviWLN54/edit#gid=707766415
then inflated their estimate and added term.
TBH, this is just another example how you like to fashion yourself as the smarted person in the room. None of us will ever know until the players actually sign. You first say that they will not perform as well, and you could be correct no one knows, maybe they all turn out to be Cody Hodgson! Then you say they will not sign for this inflated salary. You will continue to push for reasons to be critical no matter what the post may be.
This post is not perfect obviously, I do not know what will be the perfect post, but this team cost nearly nothing and is better then last years team with out giving up significant assets.
