Summary
As he ages into his mid-thirties, Scott seems to be on the back-end of his career. His minutes have gone down over the past few seasons, and hasn't provided the level of scoring off the bench that the 76ers hoped for. The majority of Scott's shot attempts come from three-point range, and while his 36% over the past two seasons is above-average for a big, it's not elite and is down from the 40% he shot from 2017-2019.

Scott has never been a good defender, and has become even more of a liability as he has aged. Not only is he slow-footed and a liability on the perimeter, he doesn't provide any rim protection either. Scott will likely have some interest from teams looking for a big that can stretch the floor, but I think his offers will be around the minimum.
 
Cap Considerations
Scott will be an unrestricted free agent with a $9.5 million cap hold and full Bird rights. Since the 76ers will be operating over the salary cap, they will retain Scott's Bird rights, and have no restrictions on re-signing him.

Other teams will have multiple ways to sign Scott as even teams without cap space could possibly use any of the Non-Taxpayer MLE, Taxpayer MLE, or possibly even the Room MLE or Bi-Annual Exception to sign him. There's also a chance that Scott ends up settling for the minimum.
