What's most important to me is that they bring ingredients to the team.
Matthews, JT, 88 don't PK
I don't particularly want Mikhayev back, or Hyman for that matter. Spezza might take a draw but he's not a real PK guy. Our special teams have been a weakness, so important that whoever comes in can give us those qualities.
Why don't you want Mikheyev back when he is one of the better guys in the league at PK? Especially when you are concerned about said PK. Maybe he is not a long term commitment or anything, but he is making 1.6 mill and can at least be a high quality 4th liner. I doubt you find better in UFA for the same money.
We are on the same page. I think everyone needs to fill some kind of role effectively.
Mikheyev - shutdown and PK specialist. Someone you can just put in your own end and use to break out because he can blow past people, and does not give up much even if he is not scoring a ton either.
Semyonov - faceoff and PK specialist. Just get him to take draws and get off, or use him as a 5th PKer. If he can kill 10-11 minutes a game without giving up much, and occasionally pots a few at the other end, we have a perfect 4th liner making near league minimum. If not, then look at Brooks to do the same.
Spezza - faceoff and PP/PK specialist. Same as Semyonov, except he is right-handed and more offensive than defensive.
Not saying this should be the lineup, but just take a look at this lineup for example:
Hyman - Matthews - Marner
Bunting/Galchenyuk - Tavares - Nylander
Goodrow - Haula - Granlund
Mikheyev - Semyonov - Spezza
Rielly - Brodie
Muzzin - Holl
Cole - Liljegren
PP: Hyman, Matthews, Marner, Bunting/Galchenyuk, Tavares, Nylander, Granlund, Spezza, Rielly, Liljegren
PK forwards: Hyman, Marner, Mikheyev, Goodrow + Haula/Semyonov/Spezza for draws/#5 PKer
PK defense: Muzzin, Holl, Cole, Brodie + Rielly/Liljegren for #5 PKer.
EN: Matthews, Marner, Tavares, Nylander, Rielly, Spezza/Granlund/Bunting/Galchenyuk/Hyman (depending on the look you want).
Other than Haula and Semyonov (who still could take draws on the PK or even replace Hyman/Marner on the PK altogether), every single guy in that lineup plays some kind of important special teams role with Hyman and Marner being the only duplicates. The Leafs should be able to roll all of their lines and only need to stack up on the big 4 when they need a goal.
