Sorry...not the case.
Only the following teams could afford one of the 4 F...this is without thrm signing their UFAs. RFAs are signed to the same they were at last year. This will be off for some of these teams eith RFAs owed high salary.
These numbers are the teams signing RFAs only thrn filling out roster with $1M players.
Buffalo, Boston, Calgary, Colorado, dallas, Detroit, Florida, LA, Minnesota, Rangers, New Jersey, Ottawa, San Jose, and Vancouver.
Vancouver needs space in the short term ( next 3 yrs) so they are out, as is buffalo, New Jersey, Rangers, LA for the same reason. Detroit’s day Ottawa are rebuilding so taking these salaries doesn’t help them.
Boston, dallas, Florida, Minnesota, San Jose are left
Calgary needs to sign defense using up their space.
This is assuming you are trading one of the 4 for nothing on 23 man coming back.
