"We had multiple offers and the Chargers squashed them all," Jonathan Feinsod, one of Jackson's agents, said.
The Minnesota Vikings were willing to give up a second-round draft choice and an additional conditional pick to the Chargers, a source said. Another source said Jackson had worked out a financial deal with the Vikings.
Chargers general manager A.J. Smith said he would only trade Jackson if he received the right value and he would only make a trade with a team of his choosing.
Feinsod was critical of Smith, saying "Archie Manning had it right," a reference to Manning's reluctance to have Eli Manning play for San Diego after being drafted by the team in 2004. They call [Smith] the Lord of No Rings for a reason."
