i think it was coz in Toronto he was pushing himself too hard. He knew he was going to be traded and thus, was just out to get stats (see: crazy high shot attempts). In Sac, he knows he's a building block. Sounds corny but mentally, i think he's just at a better place. I'm very pleased with this resurgence. He's become the Paul George of the West. Im glad i have him on my fantasy team lol
