Timofey Mozgov has averaged 10.3 points, 9.3 rebounds and 1.1 blocks in seven games since being traded to the Cleveland Cavaliers.

The Cavaliers lost their first three games with Mozgov, but have since won four in a row and LeBron James believes they're now "clicking."

Mozgov's biggest impact is on defense protecting the rim.

"It's funny, I was talking to my friend the other day and I said he's probably the best, as far as big, true big," James said. "You know, Chris Bosh is a great big, Kevin Love is a great big. But I'm talking about a true, 7-foot, big guy. He's probably the best one I've played with since Z (Zydrunas Ilgauskas).

"They have different skill sets, but they both have skill. They know how to play. Some times you get a lot of bigs that are just big. He knows how to play and it's great to have him out there."

Anderson Varejao brings a lot of intangibles to the Cavaliers, but he has never been a real rim protector.

"Having a big guy to protect the rim like that is huge," James said. "It helps Kevin out, it helps us guards, knowing that if we get beat you're going to have someone protecting the rim. And he's big at all times.

"Every time you drive you know he's going to be there. Either you're going to have to make a tough shot, he's going to block a shot, he's going to change a shot or foul you. To have that kind of protection is huge for us."
