Kelly Olynyk
If not Valanciunas, then the Heat should circle back to Kelly Olynyk. Olynyk was a key part of the 2020 Finals run but was later traded to Houston in a large deal for Victor Oladipo.
Since then, Olynyk played well for the Utah Jazz before getting dealt to the Toronto Raptors at the deadline. Toronto will likely try to re-sign Olynyk when he’s a free agent this summer, but the Heat should give him a call. There’s already a proof of concept of his fit alongside Adebayo.
The problem is that the Raptors have Olynyk’s Bird Rights and will be able to offer more than the mid-level exception the Heat will likely be limited to. Even if there’s some interest in a reunion, the money will tip the scales toward Toronto.
