Sell Vince Carter now since there will be new packs today and get someone else idk who. other than that looks good to me
Try out switching Lamar's and Giannis's position because I personally like Giannis at the 4 because of his speed advantage. Also try to get another center to replace AD having Joel is a great start so maybe a Bargnani or Myles Turner can give you some good centers for cheap.
Rate my lineup + suggestions
Sell your entire team and then on Friday buy the players to get PD Giannis, then sell those players back and buy your team back but you wont need diamond Giannis and you could sell Diamond AD for someone like a Amythest Bargani or an Diamond Marc Gasol
