From the outside looking in the Sabres management is extremely hit or miss on their signings. Mostly miss on the large budget deals. They most definitely overspent on on Skinner, but that may rectify itself next year as he has traditionally yo-yo'd scoring from year to year. This year is likely going to be his worst offensive output as a pro and that has to be a bit of a worry. He's 27 now and if you are going to spend big money you do it at this point in his career, what should be his prime. Next year if he doesn't hit 40 points, then its going to be time to hit the panic button.
You can't say this team hasn't tried to bring in talent, they brought in Okposo and Moulson when they were at their peak which is when you try and lure talent away. Sheary was nabbed in a trade as a complementary player that you figure he puts in reasonably good numbers with Eichel, but that hasn't happened. Kruger signing was a wise one, but his choice is probably going to be construed as poor as the results have been marginal. The Sabres are on an 82 point pace which is 3 more wins than last year and a goal differential of -24. They were -45 last year.
The good news for Buffalo is they aren't as cap maligned as some other teams. They can rectify the team's roster deficiencies sooner rather than later if they can overcome that 'Buffalo sucks' stigma and get UFAs to sign with them. Buffalo has 6 UFAs right now on their roster and they should look at moving any and all of them at the deadline that they can for assets. If they can move Hutton who is a UFA after this season they should as well. Hutton as a majority starter has been a failure, but as an experienced back up and a price tag under 3 million with 1 year left on his contract should net a pick.
This off season is going to have plenty of talent available in the UFA market, Hall, Hoffman, Krug, Pietrangelo, Dadonov, Kreider, JG Pageau, Toffoli, Barrie, with Holtby and Lehner leading the goalie market. While I don't think they should sign a goalie, all of the rest are guys that can improve the team. What they can't do is just throw money away. Hall's probably not going to sign there unless you throw excess amounts of cash at him, but pretty much any of the other skaters I could see in a Buffalo uniform.
