The San Francisco 49ers have been speculated as one of the teams that are most likely to pursue Philadelphia receiver DeSean Jackson in a trade.49ers general manager Trent Baalke denied reports that the 49ers have called the Eagles about Jackson for the second time at the NFL owners meetings on Tuesday. Jackson's huge contract is one of the reasons the 49ers are likely reluctant to pursue him.However if there were no restraints, the 49ers would be a terrific fit for Jackson.
