Kemp is currently on the disabled list for the second time this season, although the Dodgers have maintained the best record in baseball. Ethier and Kemp anchor the Dodgers' defense, with Ethier in center and Kemp in right.
"They've got a quiet competitiveness and great respect for one another," Colletti said.
Ethier added, "I can look up and know where Matty's at most of the time. You don't see that often in baseball where two guys can do it defensively as well as being at the same level offensively."
Ethier and Kemp's relationship dates back to when they played on the same Arizona Fall League team, although Ethier belonged to the Oakland Athletics and Kemp was with the Dodgers.
"It's unbelievable to know I'm going to get the chance to play by his side for the next five years," Ethier said. "Me and Matty know we have to go out there and do our thing. When you start adding other key guys it definitely does allow everyone around you to play better baseball."
Ethier said he knew from the start of spring training that good things were in store for the team after the last few years of turbulence under McCourt.
"You could definitely tell by the way this group came together this spring," he said. "By far this is the best clubhouse and best group of guys in the seven years I've been here. I want to give them a lot of credit for the start we've had and the start I've had."
Ethier also gets use of a luxury suite at the stadium eight times per season for community and charity work in the Los Angeles area.
