I will pretend that ATL can't just sign Hayward and go with the idea. Like others, I'm a fan of Collins, but the deal has to be for Capela, doesn't it? As it stands, Collins is mostly a PF, but Capela, Okongwu, and Dedmon are all definite Centers. No way we deal Hayward for Dedmon.
I understand the concerns about Capela's range, but he would be amazing in his role on this team. Having that kind of defensive presence on the back line, along with his ability to switch on the pnr would be super-helpful on a team full of offensive stars.
