Wade
Winslow
Green / Deng
Bosh
Whiteside
I think Whiteside and Bosh are both athletic, big, and good enough to be the kind of defensive force that can handle the switches, the running in transition like Draymond does, and can abuse Draymond and Barnes.
The biggest problem is that you can probably hide Curry on Winslow but Whiteside and Bosh is a nightmare matchup for Barnes and Green. Bosh is a great PnR defender, is one of the best bigs you can ask for at switching onto guards.
But I'm obviously stanning right now. I actually think the Hawks match up decently against them as far as the small ball goal.
