2019 2nd round pick
2019 or 2020 conditional 1st round pick
2021 conditional 1st or 2nd round pick
2022 conditional 1st round pick
Comment: The 2019 2nd rounder is the better of San Jose's own or Florida's own, previously acquired. If the Sharks miss the playoffs in 2018-19, the 2019 or 2020 first-rounder will be in 2019; otherwise, it’s a 2020 first-round pick that will go to Ottawa. If the Sharks re-sign Karlsson the Senators receive a conditional second-round pick in 2021 which would become a first-round pick if the Sharks make it to the Stanley Cup Final in 2019. If Karlsson is on an Eastern Conference roster (reserve list during the 2018-19 season, the Sharks would have to send the Senators an additional first-round pick no later than 2022.
