Which players would you want to fill the big salary slots next season?

[RodyTur10]

Currently we have a TPE (28.5M), which expires November '21 and Kemba Walker (max contract).
That's a lot of salary to 'fill'. The assumption here is that the Celtics keep Tatum and Brown, so we're looking at complementary pieces.

Who do you want to see on the Celtics payroll next season using that salary space?
Of course you can opt to keep Walker.

Please name just 2-3 players and make it realistic (not: Mitchell and Jokic  ).

If I were to guess for the sake of optimizing every penny out of the $28.5M tpe -
Rubio - $17.809M
Nance - $10.691M
These are their next season salaries.

While the two players fit exactly to the penny they might be relatively cheap to obtain and fill positions of need.
Rubio might cost yam madar rights and Carsen plus $
Nance - GW + 2/3 second round picks.
