Mike Zimmer couldn't hold back his frustration after Sunday's 21-10 loss in Philadelphia.

Realistically, big picture-wise, he should feel fortunate. Not that his team isn't any good. We've seen these Vikings coming for awhile. But his offense, minus so many pieces that have been subtracted due to injuries, hadn't turned the ball over once in its 5-0 start.

That's when Eagles defensive coordinator Jim Schwartz, who'd seen Sam Bradford for all of training camp before he was traded a week before the opener, dialed things up. The result? Four turnovers, including Bradford's first interception of the season, coupled with a pair of fumbles. Schwartz doesn't have as many pieces as the Vikings' defense, but he had enough to sack Bradford six times, deliver 19 hits and 14 knockdowns.

Bradford's managed to step in for Teddy Bridgewater more easily than starting tackles Matt Kalil (hip) and Andre Smith (triceps) have been replaced. T.J. Clemmings is capable after starting all of his rookie season a year ago, but the hope that former No. 1 overall pick Jake Long had anything left took a serious hit Sunday. He'd gone unclaimed for quite a while (even reportedly going through a workout with the Bears), and we saw some of the reasons against the Eagles. He was replaced by journeyman Jeremiah Sirles. The middle of that line seems OK, thanks in part to the free agent signing of guard Alex Boone to anchor the interior with Brandon Fusco and center Joe Berger.

The great Adrian Peterson's torn meniscus in week two has him on injured reserve, with little hope he'll make it back. And while Jerrick McKinnon (3.2 yards per carry) and Matt Asiata (3.3) are serviceable, the line hasn't been able to help those replacements rush for an average of even 75 yards per game (31st in the NFL).

And think about this: Yes, the Bears have played one more game than the Vikings, but they have four receivers who've matched or surpassed the dangerous Stefon Diggs' team-leading total of 27 receptions. Three of Bradford's seven touchdown passes have gone to tight end Kyle Rudolph. Former Illinois High School Player of the Year Laquon Treadwell was targeted to be the big target Bridgewater/Bradford needed, but had just two snaps the first three games and has yet to catch his first NFL pass. It's part of the Zimmer Way to bring along draft picks slowly (think Trae Waynes last year, albeit at a much deeper position on this team). Zimmer's indicated the 23rd overall pick's still too mechanical, still thinking too much at this level to earn snaps over Adam Thielen, Charles Johnson and now, even the once-exiled Cordarrelle Patterson, who scored the Vikings' lone touchdown Sunday on a pass from Bradford.

Like the Bears, this banged-up unit has trouble in the red zone (touchdowns on just 47 percent of their trips inside), and their 21.5 points per game average is boosted by four touchdowns combined from its defense and special teams. It'll be interesting to see if Leonard Floyd, Willie Young and perhaps Pernell McPhee can have themselves a good night next Monday against that susceptible line, and who's able to go among the Bears' defensive backs versus a passing offense that's averaged only 225 yards a game.
