Erik Karlsson Francis Perron	September 13, 2018	Josh Norris Chris Tierney Rudolfs Balcers Dylan DeMelo 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.
