PHILADELPHIA — Head coach Chip Kelly isn’t counting, but the Philadelphia Eagles hit the bye week as proof that numbers do tell the occasional fib.

The Eagles are 24th in total defense and already have given up 13 touchdown passes, the third most in the NFL through six weeks.

They lead the league in giveaways (14) and have the fifth worst turnover differential in the league. They are 29th in red zone offense, converting just eight of 20 inside-the-20 opportunities into touchdowns.

They are 21st in third-down defense.

The offensive line, which had zero missed starts last season, has 13 and counting heading into a Week 7 bye.

LeSean McCoy, who ran away with the league rushing title a year ago, was averaging just 2.9 yards per carry before finally busting loose for 149 yards Sunday against the New York Giants.

Nick Foles, who had the third-highest passer rating in NFL history last season (119.2) and led the league in just about every pertinent passing category, is 25th in passing, 28th in completion percentage and 25th in yards per attempt and interception percentage.

And yet, the Eagles are 5-1, rewarded by Kelly with a full week of freedom before reporting back to the team’s South Philadelphia facility next Tuesday.

Asked to explain how his team has managed to win five of its first six games and be tied with the Dallas Cowboys for first place in the NFC East despite all of the previously listed failings, Kelly said, “We don’t have to explain. You are what you are.

“I don’t worry about that. We don’t go in after a game and say, ‘OK, let’s tell everybody the reason why (they’re 5-1). You don’t have to explain it to anybody. Your record is what it is. You look at the standings and that’s your record.”

The Eagles are off to their best start since 2004, and they’ve done it in a most unusual way — with comebacks, erasing double-digit deficits in each of their first three games.

They’ve done it with special teams. Their special teams units already have scored four touchdowns, including two on blocked punts.

They’ve done it with unexpected help from backups. Center David Molk, who is subbing for injured Jason Kelce, and left guard Matt Tobin, who is filling in for injured All Pro Evan Mathis, had never started an NFL game before being thrust into their current roles. Despite that, the Eagles have given up just seven sacks in six games.

Inside linebacker Mychal Kendricks, probably the Eagles’ best defensive player, has missed four games with a calf injury.

Defensive coordinator Bill Davis replaced him with not one, not two, but three different players — Emmanuel Acho, Casey Matthews and dime linebacker/cornerback Nolan Carroll. On Sunday night, without Kendricks, the Eagles recorded their first shutout in 18 years.

Kendricks is expected to return after the bye for the Eagles’ Week 8 games against Arizona. Mathis, who is on the team’s short-term injured reserve list with an MCL sprain, and Kelce, who is recovering from sports hernia surgery, both hope to return in Week 10 against Carolina.

“We’ve had a good start, but we need to continue,” said Kelly, whose team has won 12 of its last 14 regular-season games dating back to last season.
