I think there are a lot of solid options, but the ones that stick out to me are firstly Kyle Kuzma. I've always been high on him, and I think getting more opportunities to show his stuff will be huge for him. Keldon Johnson is another solid pick, should get more PT with Derozan (assumedly) out of the way. I know I already went with a Wizards forward but Rui Hachimura has the talent and athleticism and I bet it comes together soon.
Toughest award to predict, let me know who you got!
