I don’t know what “free agent” means in that statement but Jonas Valanciunas recently recovered from covid and seems like a trade deadline candidate?
Add from Wikipedia:
“On 11 July 2019, Valančiūnas signed a reported three-year, $45 million contract with the Grizzlies”
So he’s signed for $15M/year til 2022? He’s just 28 years old too. If Memphis decides to start developing their young guns then maybe he could be on the trading block sooner rather than later.
