Is there any realistic reason to hope Knight fall to 7th?
Well, I suppose it's not impossible. Let's throw this scenario out there:
Cleveland - Kyrie Irving (BPA)
Minnesota - Derrick Williams (BPA)
Utah - Kawhi Leonard (empty cupboard at SF, sorry Hayward!)
Cleveland - Enes Kanter (have no center)
Toronto - Kemba Walker (choose Kemba over Knight)
Washington - Jan Vesely (supposedly high on him)
Kings - Brandon Knight
That's not too far out of the pale. But I think it would absolutely depend on the Jazz not going for a PG at #3 and the Raptors choosing Kemba at #5. Washington at #6 (Wall) and Cleveland at #4 (Irving) won't pick PGs, nor will Minnesota at #2 (Williams BPA).
I think my worst-case scenario is:
Cleveland - Kyrie Irving
Minnesota - Derrick Williams
Utah - Brandon Knight
Cleveland - Enes Kanter
Toronto - Kemba Walker
Washington - Kawhi Leonard
Kings select between Biyombo, Valanciunas, Motiejunas, Vesely, ???
In that scenario, I don't know what we do. There's a guess that Valanciunas might stay in Europe for a year, and I know we're looking for help now. Motiejunas seems soft, Vesely can't shoot, Biyombo is an athletic specimen but has zero offensive game and is likely redundant if both Dalembert and Whiteside are back. I'm not as high on Jordan Hamilton as some here, not at #7. If that happens I think I wouldn't be unhappy about trading down.
In fact, my feeling right now is that Irving, Williams, and Kanter cannot fall to us. If neither Knight nor Leonard fall, I'm not high on the options left (including Kemba) and I'd be down for a trade of the pick. Fortunately, Kemba, Valanciunas, Vesely, and Biyombo might catch somebody's eye above us and allow one of the Knight/Leonard target to fall. Right now, I think that's much more likely Leonard, though.
