Taylor Hall Blake Speers	December 16, 2019	Nate Schnarr Nick Merkley Kevin Bahl 2020 conditional 1st round pick 2021 conditional 3rd round pick
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.
