SEATTLE -- Following the Sam Bradford trade to the Minnesota Vikings, Philadelphia Eagles head coach Doug Pederson offered the following explanation for why the team felt comfortable starting rookie Carson Wentz right out of the chute.

"We got a good football team around him, got a great defense, special teams, offensive line, good runners. All the pieces are here for him to be successful and for us to win some games," he said.

Now 10 games in, it's clear that Pederson's statement was not entirely accurate. The defense and special teams are legitimate as he said, but the pieces around him offensively have made for some unnecessarily tough sledding for the No. 2 overall pick out of North Dakota State.

That was evident in the Eagles' 26-15 loss at the Seattle Seahawks Sunday. Topping the Seahawks at CenturyLink Field was a tall task for the first-year signal-caller coming in, and turned into a near-impossible feat when the players around him began to break down. The most glaring example was Nelson Agholor's failure to line up properly on a would-be 57-yard touchdown to Zach Ertz in the second quarter.

"I mean, it's frustrating. You would think you can get lined up, that's the basics of football," said safety Malcolm Jenkins.

But it wasn't the only one. Fellow receiver Bryce Treggs lost track of the ball and slowed his pattern up as Richard Sherman hauled in the interception deep down the field. As has been the case for most of the season, the skill position players struggled to separate from defenders and were guilty of several drops.

Wentz's play has regressed while working alongside this supporting cast. Wentz went 2-of-13 with two interceptions on passes thrown more than 10 yards downfield Sunday, with his first completion coming at the 7:15 mark of the fourth quarter, per ESPN Stats & Information. He has not thrown a touchdown on such passes since Week 3. Wentz owns the worst Total QBR in the NFL since Week 5, throwing four touchdowns to six interceptions over the last five games after tossing seven touchdowns to one pick over the first five.

Lack of discipline and precision has been an issue for this offense, especially on the road (the Eagles are now 1-5 away from Lincoln Financial Field). Some of that can be traced to collective inexperience. On the Agholor illegal formation, for example, Pederson said when it comes to responsibility, "it's a little bit of [Agholor], a little bit of the quarterback, a little bit of me." Problem is, you're talking about a second-year player, a rookie quarterback and a first-year head coach. Pederson also instructed Jordan Matthews after the play that, as the senior member of the group, he needs to take it upon himself to make sure Agholor is lined up right. But Matthews is just 24 himself with two-plus years logged in the league.

It's the green leading the green, and it's been an issue. Ideally, you would want a more seasoned -- and talented -- group surrounding a young quarterback.

The man in charge of supplying Wentz with the necessary weapons is Howie Roseman. Speaking to the media on Friday, the executive vice president of football operations was asked to evaluate Wentz's play through a half-season plus. Tellingly, he shifted the answer towards the personnel around him.

"Carson has been what we thought he would be on and off the field. All the stuff that we saw when we evaluated him: tremendous work ethic, leadership, the physical skills. The ceiling just keeps getting bigger for him," said Roseman. "It's about the team and making sure that the team around him is taken care of as well. That's what we're trying to do. It's such a team sport. You've got so many guys on this team; it's different than basketball. That's our job is to make sure that we're getting a team built around him so that we've got a chance to compete here."
