I think the Heat part is likely fair. Although Robinson has actually been playing really well for them, so even with his ugly contract, can see them being ok with it since he's a big help in spreading the floor.
I don't think Indy would pay that much, however for Grant. 2 picks seems like an ask already, more of what it'd take for us to move him, but not what they'd pay for him. But also, Hield is still a useful player, who they may be able to land a pick for if they wanted, which almost makes it 3 1sts for Grant.
Maybe they keep a 1st, and send Jovic to Utah so they get 3 1sts and a young player for Lauri.
I also think this pushes us into the LT, which seems very unlikely in a lotto year.
