With the big-spending period of free agency in the books, let's take another look at our San Francisco 49ers' mock draft for the first round.The 49ers will have the 30th pick in the first round of the draft, which takes place May 8-10 at Radio City Music Hall in New York City. Based on the events of free agency, I am changing my direction as far as the target position goes.Mock draft pick Take I: Penn State receiver Allen RobinsonMock draft take II: Oregon State receiver Brandin CooksMock draft take III: TCU cornerback Jason VerrettWhy: The 49ers' need for a speed receiver remains.
