Kyrie Irving-led Cavaliers beat Pistons 105-89

"You feel like you let the fans down," Frank said.

Detroit lost its opener by 12 points at Indiana.

"This doesn't get fixed in two weeks," Frank said. "This is going to take a lot of work."

Cavs owner Dan Gilbert, who like Gores graduated from Michigan State, attended the game and spoke with a handful of reporters before the game.

"We're definitely committed to the rebuilding process right now," Gilbert said. "We want to build through the draft and we love the corps of young guys we've got."

The Cavs beat Detroit in the 2007 Eastern Conference finals to play for their first NBA championship, reached the conference finals two years later, lost in the second round in 2010 — then were spurned by superstar LeBron James bolting from his home state team to play in Miami.

Gilbert said James' decision to leave as a free agent seems like "10 years ago" and insisted he only thinks about him when Cleveland plays the Heat.

"We're just really focused on the future and rebuilding the franchise and doing it for the long haul," Gilbert said.

NOTES: The Cavs added guard Manny Harris to their NBDL team, the Canton Charge. They cut the former Michigan star after he missed training camp with a burn on his right foot that Cavs doctors couldn't treat during the NBA lockout. ... Detroit Lions defensive tackle Ndamukong Suh was featured during a part of the pregame festivities and watched the game from a front-row seat.
