In a vacuum I'd take their roster over ours for sure, if we're not gonna count anything else.
Talented big men are hard to find in this league. They have both front-court spots set for the future with Gobert and Favors. Gobert is just an animal. He has DPOY candidate written all over him. Finding a C to anchor your defense who's that good at that age is HUGE. And Favors is developing well now too. Good defender, solid offensive output, still improving. A better player than Sully, that's for sure.
Utah's roster has things we lack. We need a defensive minded presence down low and a wing who can score, create and at least be average on D. They have Gobert, Favors and Haywood, all guys whom if we had them would make this team considerably better. Now, they need back-court help which is our strength. It's still too early, but that Exum over Smart pick looks worse by the day. I like Trey Burke off the bench, Burks has a place in the league. Considering our SF situation I wouldn't mind having Hood. All in all I like the Cs outlook better in the long term, but Utah has the better roster for a rebuild today.
If I was doing that 10 it might be like
Gobert
Haywood
Smart
Favors
Thomas
Sullinger
Bradley
KO
Young
Burke/Hood
