Mavs GM Nico Harrison on signing players via buyout: ‘We’ve done our homework. So we think we know who’s going to get bought out. But at the end of the day, we have 15 roster spots already filled. And for us to bring somebody in whoever that person could be, we’d have to release somebody. And I don’t think we want to do that. I think we like we like our roster how it is. And there’s nobody that I would feel comfortable releasing at this point to add room for somebody else.’
