If it came to the second half of the season and we were still looking bad I'd David Robinson the Jays for a chance at one of the top picks.
I'm a huge fan of Jalen Duren. He's 6'10, 250lbs and has a 7'5 wingspan, while still 18. He's immensely athletic, chases rebounds and patrols the paint defensively really well. For comparison, he's around 18 months younger than Holmgren yet looks far more NBA-ready in terms of physique. Reminds me a lot of Dwight Howard.
Jabari Smith reminds me a lot of Michael Porter Jr. That long, silky offensive-minded forward who is a decent but not great athlete.
I love Paolo Banchero too. I think he'll end up like a much stronger Tobias Harris (he's already 250lbs). Offensive nightmare match-up.
Nikola Jovic reminds me a bit of Toni Kukoc, which would be great alongside the Jays. Can shoot, drive, has good court-vision and a soft touch finishing in the key.
There are a few more, like AJ Griffin, Dieng and Collins.
