MANKATO, Minn. (AP) _ The Minnesota Vikings' high-powered offense is more than just the best trio of wide receivers in the NFL.

Try the deepest depth chart at quarterback.

	Randall Cunningham hopes to build on last season's tremendous success.

Behind starter Randall Cunningham, who is coming off his best year ever, is: Jeff George, who just two years ago threw for 29 touchdowns; rookie Daunte Culpepper, the franchise's future; and Todd Bouman, who lit up NFL Europe this summer.

New offensive coordinator Ray Sherman, who toiled with the Pittsburgh Steelers and erratic quarterback Kordell Stewart last season, said he's never seen a team with so many strong arms at quarterback.

"Not like this," he said with a smile. "I love all of them. We're very fortunate to have a group of guys like this. Some teams don't have two. We're fortunate to have four.

"They all have strong arms, and for our offense that's what you need," Sherman added. "Every one of them has the arm to get the ball where we want to put it."

And that's into the capable hands of Cris Carter, Randy Moss, Jake Reed and fourth receiver Matthew Hatchette, the deepest and most talented group of wideouts in the NFL.

The depth at quarterback provides coach Dennis Green with injury insurance.

"That means that regardless of what happens, you got a guy that can go on the field and play and still have success in our offense. That's important to our style of play," Green said.

Carter said the quarterback depth will be especially evident -- and essential -- during training camp.

"It's really nice because I think offensively the cohesiveness from unit to unit will be better," Carter said. "And the efficiency of practice is better because you have quality people throwing the ball at all times.

"The second-unit receivers, third-unit receivers, they get better balls thrown to them. And I think you'll really see that in the preseason. I think you'll see our second- and third-team receivers and quarterbacks play at a higher level than the other team."

All four quarterbacks have been impressive during the first week of drills, when the out-of-sync offense usually struggles to keep up with the defense.

The zip of George's throws have been particularly impressive, as have Culpepper's work habits.

"Jeff is a phenomenal talent," Carter said. "Daunte's young. He's got a lot of time to grow. He's in a great situation where he can learn, not a lot of pressure on him."

Green said he's been impressed when Cunningham gives way to his bevy of backups, too.

"George has been wowing us with his arm," he said.

And nobody's working harder than Culpepper, who signed a five-year, $7 million contract that could grow to more than $19 million with incentives.

"Daunte Culpepper is amazing. He's the first one on the practice field and the last one off it," Green said.

And of course, Cunningham is coming off the best season of his 14-year career, a monster year in which he threw for 3,704 yards and 34 touchdowns, and he no longer has to worry about being Brad Johnson's backup.

"Randall told me he feels good, he said he's never felt better," Moss said. "And he told me he's been working hard. I'm ready for Randall. I'm so happy our whole offense stayed together."

The one that scored an NFL record 556 points last season.

Green said Culpepper will get some game action this season, but he hopes that it's during garbage time when games are well in hand.

Still, Cunningham knows the best way to make another run at his and the franchise's first Super Bowl title is for him to keep his backups on the bench and with him coming out only for a breather, not an injury.
