According to Charania, Warriors head coach Steve Kerr also spoke with Cousins on the phone before he agreed to a one-year, $5.3 million deal.
While Cousins is the newest member of the Warriors, it's unclear when he'll actually make his debut for Golden State. The four-time All-Star hasn't played since suffering an Achilles injury in January.
Charania reported the Warriors hope Cousins can suit up in the "early part" of the 2018-19 campaign and that the playoffs are when his true value to the squad will be evident.
Should Cousins get back to being a double-double machine, the Warriors will be even more dominant than they were en route to back-to-back titles.
