CHARLOTTE, N.C. -- Atlanta Falcons owner Arthur Blank has expressed full support for coach Dan Quinn in the wake of a lopsided shutout amid the team's slide to a 6-7 record after beginning the season with five straight wins.

"I've got complete confidence in Dan," Blank told ESPN.com after his team's 38-0 loss to the undefeated Carolina Panthers. "He's going to be a great head coach for us for many years."

Quinn, the former Seattle Seahawks defensive coordinator who signed a five-year contract, called Sunday's loss unsuitable on all levels.

"I think No. 1, it was totally unacceptable for everybody, that's the coaches and that's the players," Quinn said.

The Falcons, who haven't made the playoffs since 2012, have dropped six straight games and stand eighth in the six-team NFC playoff picture.

"Basically the message going back to the team is everything counts -- look smart, tough, and finish," Quinn said. "That's what I expect from our club and that's what we will get done."

During Sunday's loss, the Falcons were dominated at the line of scrimmage on both sides of the ball, an aspect Quinn vowed would change under his fast-and-physical philosophy.

Blank was asked about Quinn's status in the context of an online story that mentioned numerous possible head-coaching vacancies following the 2015 season.

"I didn't read it. I didn't write it. I'm not thinking it,'' Blank said. "I don't know anything about it. And most importantly, I'm not thinking that."

Quinn, who was given final say over the 53-man roster, eventually will have to weigh what changes need to be made. Those might include tough decisions with the coaching staff, where offensive coordinator Kyle Shanahan has taken much criticism for an offense that has scored just two touchdowns the last three games.

Shanahan signed a three-year contract, and Quinn last week expressed confidence in Shanahan's offensive mentality even despite Matt Ryan's struggles adjusting.

Changes in the front office appear inevitable, with general manager Thomas Dimitroff stripped of his power following Quinn's arrival.

Blank said he was pleased with the partnership between Quinn and Dimitroff early in the season, but that was well before the downward spiral started for the Falcons.
