The Vikings have already agreed to $81 million in contracts in signing free agents this offseason, including $30 million guaranteed.
But owner Zygi Wilf has given the go-ahead to spend the money to sign Kansas City defensive end Jared Allen, who as the Chiefs' franchise player is guaranteed $8.8 million for this season.
It likely will take a multiyear contract averaging at least $10 million a season, plus at least $25 million in guaranteed money, to sign Allen, who had an NFL-high 15 1/2 sacks last year and singlehandedly could make the Vikings defense one of the best in the league.
The other issue is what the Chiefs will demand in exchange for Allen. Wilf won't object if the Vikings give up first- and third-round picks in the upcoming draft in exchange for the 26-year-old, who has had some off-the-field problems, with two drunken driving arrests in 2006 that led to a two-game suspension.
"This is a complicated situation," Wilf said. "But if we can work it out, we will spend the money."
Wilf got involved immediately when he was told that Allen was available.
Wilf flew to the Twin Cities on Thursday in his private jet to pick up coach Brad Childress, defensive coordinator Leslie Frazier and defensive line coach Karl Dunbar. They all flew to California to pick up Allen and his girlfriend. When they landed in Minneapolis, there was a limousine ready to take Allen to Winter Park.
"We spent 6 1/2 hours in the air on Thursday," Childress said.
