The cost of adding Jean-Gabriel Pageau to the New York Islanders lineup at the 2020 NHL trade deadline was a 2020 first-round pick, a 2020 second-round pick, and a 2022 third-round pick.
That first-rounder was top-three protected incase the Islanders fell out of the playoffs and somehow moved up into the top three at the draft thanks to the lottery. That 2022 third-round pick would only go to the Senators if the Islanders won the cup in 2020.
So because of the Pageau trade, the Islanders won't make a pick at the 2020 draft until the third round.
