Not sure why the defensive metrics show poorly for Prince. He's been known as a good defender. He can hit the 3 too. He's a good all-around player and still really young.
I would offer WCS for him straight up. Maybe mix and match some other pieces in the deal to acquire Lin in the process if possible.
Hawks could have insane high-flying frontcourt athleticism in Collins and Willie, with Trae dishing lobs left and right.
We fill our gaping hole at SF.
So WCS, Mason, Ben 11.5 mil works on RealGm and a 2nd rd for Lin, Prince 16.2 Mil Sal
Lin might be a small upgrade over Yogi
Both Yogi and Mason are non-guarenteed next yr, so If Lin will take Backup salary, I am ok with him as long term Backup PG
If he wants the big bucks, then just keep Yogi
Prince might also be a small upgrade over Shump and JJ
He is only 24, potential, contract cheap thru next year
If we get a better SF in FA, he would be a good backup
Its a great short term solution to both Backup PG, and SF Needs
Other than Collins, Atlanta Bigs suck,
