I honestly don't love the idea of adding another wing, but I am all about adding a 3rd star. Siakam would be #1, followed closely by Ben. Also would be great to get Grant at a discount, but I have no idea how DET values him. Could probably live without Wood for now since we have TL and Horford.
Funny enough, we could really a use an All-Star caliber PG. I am all set watching Tatum and Brown trying to run the show. They aren't horrible, but are secondary playmakers at best. Both would be so much better coming off picks rather than always trying to create for themselves. Same with Smart obviously, but he'd very likely be going out in any trade for a high salary player.
