Agreed on Horvat being the ideal target. If NYI decide to re-tool, it makes sense to sell him, since he was acquired to push them as a contender.
Extend Boeser and Suter, if the number is even just ok - something like 4M for Suter, and just under 8M for Boeser with a NTC (I think his anxiety about being moved was an issue before, so if it gets his AAV down, a NTC for him would be fine).
This would leave just over 10M for Horvat, a Raty extension and a Forbort replacement. If they don't send cap back to NYI, the cost to acquire should be fairly minimal (prospect(s) + non-1st round pick(s)). Would be tight, so maybe explore moving Blueger or Hoglander, but theoretically they could look like this next year:
Debrusk-EP40-Boeser
Hog-Horvat-Garland
Joshua-Suter-Sherwood
O'Connor-Raty-Lekk
Chytil (if healthy, could run a Hog-Chytil-Sherwood 3rd line and move Suter to 2LW)
Hughes-Hronek
MP-Myers
EP(D)-Willander/Mancini
League-min Forbort replacement
Demko
Lankinen
^That team, if they don't get decimated by injuries like this year, and EP40 somewhat returns to form, should be very, very good
