GREEN BAY, Wis. -- Mike McCarthy lost the first three home games of his head coaching career.

“I can tell you that there’s not a worse feeling in my coaching career [than] walking into that tunnel after a loss,” McCarthy said of losing at Lambeau Field. “Trust me, it hits all of us.”

Imagine what it will feel like if the Green Bay Packers lose Sunday at home to the Tampa Bay Buccaneers. For the first time since 2006, McCarthy’s first season, the Packers have lost three straight at home. A loss Sunday would give them their first four-game losing streak at home since 1991 -- and not all of those home losses that year were at Lambeau because the Packers still played three times a year in Milwaukee back then.

Here’s how bleak things look for the Packers (5-6): They’re a slight underdog at home against a 4-7 team that’s in last place in the NFC South by three games.

The three straight home losses all have been unsightly -- 26-17 to the Saints, 30-17 to a Lions team that had won once in Wisconsin in the previous 24 years, and 23-0 to the Ravens, who became the first team to shut out the Packers since 2006.

“It’s kind of hard to lump them all together,” McCarthy said when asked about the Lambeau losing streak.

The common denominator, of course, is Aaron Rodgers, who hasn’t played since his Week 6 broken right collarbone at Minnesota. But even in 2013, when he broke his left collarbone, the Packers won once and tied once at home without him.

Their only win this time came at Chicago, and the Bears haven’t won since then.

“At the end of the day you have to go back through the games,” McCarthy said. “It’s part of the challenge of this year. There’s no, ‘Hey, this is what you’re doing at home’ type thing. There’s a bunch of challenges that we’re fighting through this season, and we’ve had some tough games at home.

“The Saints played very well. The Lions played well and then obviously the Baltimore game. But they’re distinctly all three different games, and it has nothing to do with playing at home. I think it’s all the challenges of the adversity, and frankly all three of those teams were coming off a bye week, too, so you’ve got to look at that. You can look at it any way you want. But you need to win your games and obviously we need to win all of our games, especially these [last] two at home.”

The Packers have faced their share of boos at home since Rodgers’ injury, and Brett Hundley's numbers explain why. He hasn’t thrown a touchdown pass at Lambeau but has four interceptions and a passer rating of 59.2. On the road, he has five touchdowns, three interceptions and a passer rating of 90.1.

“We try to play our best each and every week,” Hundley said this week. “We always try to play great at home, so we’ve just got to come out and do what we’re coached to do.”
