The point is the average salary has moved so close to the cap ceiling that there may not be any teams immediately ready to be below the cap floor. If you look at capfriendly.com, with the page moved towards the 2020-21 season there are only 5 teams below the floor:
Team, roster, $ below floor
COL, 14/23, -$1.1M
NJ, 13/23, -$4.9M
BUF, 10/23, -$11.9M
DET, 11/13, -$13.4M
OTT, 10/23, -$18.3M
By the time contracts are signed and rosters filled out probably the only team that could still be below the floor is Ottawa. And like I said in my prior post if you want to be cheap another option is to acquire a LTIR player whose salary will be payed by insurance, like Arizona did with Datsyuk.
So end result, for any team right now except maybe Ottawa who will have options adding Eriksson right now means adding real $$$ to your payroll.
