Sam Bradford's weekly chat with the media isn't until Wednesday, but by then he'll probably have already spilled.

The Vikings (5-0) play the Eagles (3-2) on Sunday, just a day past Bradford's seven-week anniversary of when he was traded from Philadelphia to Minnesota.

Bradford started 14 games for the Eagles last season and spent four months this offseason as the starting quarterback under their new coordinator Frank Reich. So he's just as knowledgeable as anybody about what the Eagles offense had planned, right up until Sept. 3.

"Obviously, we're going to ask him," head coach Mike Zimmer said.

Giving inside information to the Vikings' No. 1-ranked scoring defense (12.6 points per game) doesn't seem fair. Zimmer provided one caution to guard against overthinking, which hasn't been much of a problem in their diverse defensive system.

"I think all that stuff is really overrated," Zimmer said. "I think we have to execute what we do. Some games we get signals from other teams and things like that and a lot of guys don't play good when they know that stuff. We typically kind of just play and do what we do and don't worry too much about the other team."

Bradford's knowledge of the Eagles players' strengths and weaknesses could be more of an advantage than the playbook, Eagles coach Doug Pederson told reporters in Philadelphia on Monday. The Vikings will certainly ask about both while being wary of changes made since rookie Carson Wentz took over after Bradford's departure.

"But at the same time, it's one week," Vikings cornerback Captain Munnerlyn said. "It's hard to try and install a whole new offense."

Munnerlyn said Vikings defenders will pick Bradford's brain, one that also practiced against the Eagles defense under coordinator Jim Schwartz this offseason. Bradford has enjoyed a mistake-free start with the Vikings as his 109.7 passer rating trails only Atlanta's Matt Ryan and his four games without an interception ties the longest such stretch of his NFL career.

At least on Sunday, he'll give a boost to the defense, too.

"Obviously we're always going to look for tips and how we can help the players," Zimmer said. "A lot of players play better when they focus on their keys and focus on the things that they do."
