I’ve looked at a Korpisalo trade so many times. Here’s the potential pick packages that seem to be “fair” value according to puckpedia’s cap relief values (in all scenarios I’m giving Ottawa a little surplus value, because actual fair value is so painful I think it’d be a tough sell to their fan base). Also I’m assuming Korpisalo is being valued as replacement level; or rather, bringing no value as a player.
Trade back x2
Korpisalo + 7 + 25 for 14 + 42
Ottawa gets surplus value of a mid 2nd
Keep #7
Korpisalo + 25 + 39 for future considerations
Ottawa gets surplus value of a mid 2nd
Tradeback to 14 + retention
Korpisalo 25% retained + 7 for 14
Ottawa gets surplus value of a mid 2nd
Presumably the Sharks would buyout Korpisalo. While this would leave some cap load on Ottawa, it would be greatly reduced:
$83k, $208k, $460k, $584k, $333k x 4yrs
All values would be triple for Sharks cap
