Leslie Frazier continued to accept blame for his defense's meltdown on the final drive against the Chicago Bears in a 31-30 loss on Sunday. But he also cited a lack of execution on the players part, too.

Frazier blamed himself immediately after the game for not doing more on that drive, and he continued with that theme at his Monday press conference.

Frazier remained vague on what he would have done differently, other than admitting he should have managed that situation better.

"We're talking about a sequence that was a very important sequence during the course of the game," he said. "You can't take away all the good things our defensive did yesterday. There are just some things from my standpoint that I have to manage better."

Frazier said he doesn't want to take over play-call duties from defensive coordinator Alan Williams in that situation. That's not his intent.

"Our defense was well prepared," he said. "They did a great job to do the things they did to allow us to be where we were in that ball game. So no, I don't foresee a situation like that. Alan and our defensive staff, they've done a very good job. They did a good job a season ago and they're doing a good job now."

Several defensive players were upset with the play calls on the final drive. Middle linebacker Erin Henderson said he was surprised by the play call on the game-winning 16-yard TD catch by Martellus Bennett.

Frazier said the Vikings were prepared for that look and even made that same defensive call twice in the first half.

"We called it back to back, when they tried those fade balls," Frazier said. "We just didn't execute it as well and it cost us. That's something we worked on, something we executed well in the first half, but we didn't get it executed there."

Frazier added: "We work on it in that area of the field often. We used it a season ago as well, and we used it in the first half as well. So it's a defense that we've run before. We just didn't get it executed in that situation. We have a few different things that we do with 20 seconds left, with 10 seconds left in a game and we have a couple different calls, but we do have a go-to call that they know that we like."

Patterson playing time issue

Frazier also addressed Cordarrelle Patterson's lack of playing time. A week after playing only five offensive snaps against Detroit, Patterson was on the field for only six plays on Sunday.

"We're going to get that rectified," Frazier said. "He definitely deserves to be on the field more. He's shown that in the few snaps he's gotten in these first two ball games. Hopefully, everything being equal, that should not be a part of the conversation next week. We want to get him on the field. He's one of our explosive players for sure. We see what he does when he gets the ball in his hands. We've got to find a way to get him on the field."
