Quoting: palhal
OK if 15m cap with 14 payers signed, and eight more to signed is OK...
I mean, you can run a 20 man roster-- it is not ideal but it can be done until there is enough accrual to call up an extra.
I just did a test. A buyout of Goodrow, calling up Othmann, Cuylle, Jones in for Harpur, Garand, Brodzinski, resigning motte for $1m, gives a roster of 18 with $11.2m in cap-- more than enough to keep both and add a 21st skater (say Leschyshyn/Robertson). During the offseason you are allowed to go over cap a certain percent, so the Goodrow buyout likely happens after the signings of Laf/Miller. Not only that, Cuylle, Othmann, and Garand are all waivers exempt so you can send them down during off periods to save accrual to call up a 22nd at some point.
Lines look like
Kreider-Zib-Laffy/Kakko
Panarin-Trocheck-Laf/Kakko/Vesey
Othmann-Chytil-Laf/Kakko/Vesey
Cuylle-Brodzinski-Motte
Lindgren-Fox
Miller-Trouba
Jones-Schneider
No it's not the best in the league, but it should be enough to get them into the playoffs.
