EDEN PRAIRIE — Christian Ponder stepped to the podium for his first press conference as a starting quarterback in the NFL.

“What’s up guys?” Ponder said with an easy grin. “Better get used to seeing you every week.”

The Minnesota Vikings can only hope their laid-back rookie keeps his cool just as effectively when Dom Capers unleashes Clay Matthews and the rest of the Green Bay defense on him on Sunday.

With the Vikings off to a miserable 1-5 start, coach Leslie Frazier officially announced on Wednesday that Ponder is taking over for veteran Donovan McNabb for the remainder of the season.

“It does not mean that I am giving up on the 2011 season,” Frazier said. “The decision was made purely based on what would give us the best chance to win on Sunday. That’s why the decision was made. I didn’t feel or sense that staying status quo was going to get us a win on Sunday.”

Ponder joins Carolina’s Cam Newton, Cincinnati’s Andy Dalton and Jacksonville’s Blaine Gabbert as rookie starting quarterbacks in the league.

The decision hardly came as a surprise. McNabb has struggled mightily for most of the season in this new offense and has never looked in rhythm while throwing from the pocket.

The Vikings passing offense ranks 31st in the league and McNabb ranks 29th in the league in touchdowns, 26th in yards passing and 19th in completion percentage. Frazier declined to give him a vote of confidence after a 39-10 loss in Chicago on Sunday night.

It’s the second straight season that McNabb has been benched because of his performance, but his close relationship with Frazier seems to have made this one much smoother than how things went down last year in Washington under head coach Mike Shanahan and offensive coordinator Kyle Shanahan. McNabb’s agent, Fletcher Smith, openly challenged how the two coaches handled the situation, calling it disrespectful and “unprecedented for a six-time Pro Bowl quarterback such as Donovan.”

Still, McNabb said he was surprised by Frazier’s decision and felt like he had “a lot of football left in me.”

“He is the head coach and decisions are made,” McNabb said. “At this particular point, it’s for me to continue to prepare and make sure that we continue to support Christian and make sure that he’s ready. But most important for me, is to prepare because I’m just one play from going back in. Just make sure I’m ready when called upon and try to lead us to victory.”

Ponder completed 9 of 17 passes for 99 yards in the fourth quarter against the Bears on Sunday night, his first NFL game action in the regular season. He also rushed for 8 yards and a first down to keep his first drive going, showcasing some of the athleticism that was apparent during his time under center in the preseason.

“When he got a chance to play in the game on Sunday, some of the things he did let me know that the game is not too big for him,” Frazier said. “It’s not too fast for him. He did some good things in a short period of time.”

Newton’s quick command of the offense and playmaking ability has been one of the most pleasant surprises of the season, Dalton has been a steady contributor and key to the Bengals’ fast start while Gabbert has struggled in the early going with the Jaguars.

Now Ponder will get the chance to show how he measures up to the rest of a promising rookie class.

The Vikings selected him 12th overall in April, saying at the time that the Florida State star was the most NFL-ready quarterback in the draft. All signs were pointing to Ponder taking over from the very beginning, but the summer-long lockout prevented him from getting the practice time needed to learn the offense and get on the same page with his new teammates.

So Frazier turned to McNabb, a player he got to know very well as an assistant with Philadelphia. The trust the two had in each other was one of the biggest factors in completing a trade with Washington to bring the 13-year veteran to Minnesota, with Frazier saying at the time that he thought McNabb was the best option available to help the Vikings contend in 2011.

“I can’t say that on July 31 I thought we’d be at 1-5,” Frazier said, thinking back to the day the Vikings acquired McNabb. “There’s no way I could’ve predicted that. I thought we’d be further along than we are. I have a ton of respect for Donovan both personally and professionally as well. But the decision was based on what’s going to be best for our team and what’s going to give us the best chance to win.”

Frazier said he didn’t regret his decision to bring McNabb in and was careful to point out that everyone — not just the quarterback — is to blame for the team’s struggles. The offensive line has played poorly, offensive coordinator Bill Musgrave hasn’t found a play-calling rhythm yet and the receivers lack a downfield threat to stretch the defense.

“This move is not just about the quarterback position,” Frazier said. “Our entire team has to play better in order for us to win on Sunday.”

Teammates took the news in stride, throwing their support behind the rookie and hoping the change will give them the jolt they need.

“You get to this point in the season and you’re kind of looking for a spark or something to get you going, and obviously coach Frazier and the coaching staff felt like this was something that needed to be done to get us going,” left tackle Charlie Johnson said. “So we’re behind it, we’re on board.”

Now it’s up to Ponder to make the transition from rookie backup to the one everyone in the huddle will be looking to.

“I don’t think it’s hard to do,” Ponder said. “I think at the quarterback position, that leadership position comes natural. I don’t really think anything of it. I’m just going to go out there and be the same person I’ve been for the last five years since college. I don’t think it’s going to be a tough transition.”
