Derrick Williams on the Cavs: They’re just missing the toughness. They’re missing energy and excitement. LeBron will bring that but he can’t do it all himself. There will always be five men on the court. That was a little bit of what I brought to the team last season. I brought energy, effort, efficiency. Right now it feels like there is a little bit of coasting, to be honest. It’s a long season but you can’t get bored of winning. LeBron will never get that way but you never know with other players.
