Ryan is owed $15m, Eriksson is owed $8m or $5m depending on whether you count Loui’s $3m signing bonus this season.
If we use the $5m figure then Ottawa needs to retain $3m of Ryan’s $15m remaining to achieve $7m in savings. $3m/$15m = 20% retention. Leaving Ryan with a post-trade cap hit of $6m.
How would Vancouver feel about swapping a $6m cap hit Eriksson for a $6m cap hit Ryan?
If Vancouver also buys out Ryan after the trade, it would make more sense.
To Van:
Bobby Ryan (50% retained)
To Ott:
Loui Eriksson
Bobby Ryan would then be subsequently bought out by Van.
Why Van does it:
Bobby Ryan's buyout cost is 3.5 mil cap hit for next two years then 1.8 for the following two years. Since there is a 50% retention for Ottawa this buyout cost is cut in half to roughly 1.8mil first two years and then 900k for the following two years. We would save 4.2 mil in cap space for the next two years. We would add 900k though to year 3 and 4 but there should be more expiring contracts at that point (Beagle, Edler, Roussell) and a higher cap ceiling.
Why Ottawa does it:
Instead of paying Bobby Ryan 7.5 mil in real dollars over the next two they would in real dollars:
a)Pay Loui Eriksson 1 mill (2020-2021) 4mil (2021-2022) AND
b)Pay Ryan's retention of 1.8 mil (2020-2021) 1.8mil (2021-2022) 900k mil (2022-2023) 900k mil (2022-2023)
I'd also argue that Eriksson is a more useful player on Ottawa's roster as well.
