| Comment: The 2020 first-round pick from Arizona in the Taylor Hall trade is top-three protected. Converts to 2021, if so. The conditions on the 2021 pick are as follows: the third-round pick in 2021 becomes a second-round selection if Arizona wins a Stanley Cup Playoff round OR Taylor Hall re-signs in Arizona. The third-round pick in 2021 becomes a first-round selection if Arizona wins a Stanley Cup Playoff round AND Taylor Hall re-signs in Arizona. If neither condition happens, New Jersey still receives the 2021 third-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. | ||||
