That's a lot of cheddar for just a very good player though. He's maybe a top 25-30 offensive player now, with leaky D. Maybe prime Lavine is in there somewhere still, which was a top 10-12 offensive player at one point, but given that he's about to turn 30 and his game has been based on quick twitchy athleticism and shooting while moving, I'm going to say nah on that.
Now, I think Fox has become super, super overrated....so I don't think this is an on court downgrade at all, and I think Sacto actually did really well here. Sabonis is their best player by a lot, and spreading the ball around a bit more will help them imo. Fox is a mediocre or worst point of attack defender as well, so they have a chance to do some work their before the deadline as well.
They need to trade one of Demar or Monk though...so probably Demar.
