The San Francisco 49ers have been connected to DeSean Jackson ever since reports emerged that the Philadelphia Eagles were fielding trade inquiries in mid-March.

As Jackson embarked on Day 2 of his visit with the Washington Redskins, a report emanating from NBC Washington suggested the 49ers have "thrown their hat into the ring" for the free-agent wide receiver.

Our understanding, however, is that the 49ers remain very much on the periphery.

When coach Jim Harbaugh spoke of his need for a playmaking wide receiver at last week's NFL Annual Meeting, the description sounded a lot like a Jackson scouting report.

The primary roadblocks remain asking price and salary cap.

According to NFL Media's Albert Breer, the 49ers' cursory interest won't reach legitimacy unless Jackson accepts a major discount. Matt Maiocco of CSN Bay Area has echoed that sentiment.
