Aminu is a reasonable idea to get us a genuine 3&D vet.
Some cheaper alternatives: DeMarre Carroll and Luc M&M.
Both are 34 and I'm not sure how much they have left in the tank.
But either would come cheap on short deals.
As for an additional shooter, Mirotic played last season in Spain.
He's 29, a nice stretch 4, boards well.
Maybe $5M or so gets him if he is willing to come to virusland.
Side benefit: we wouldn't be keeping Portis.
