also as part of this trade

S&T Marvin William to Ind
And
S&T J. Jack to Atl

Don't know if the second part could work and I wouldn't do it anyway.

They wouldn't consider Law for Hibbert.

It leaves only Evans as SF, unless you want Joe starting at SF with Bibby / Murray or Jack as backcourt.
IMO, this trade would only makes sense if it was following another trade.
