Word is Niners DL Ray McDonald, one of the team’s two third-round picks in the 2007 draft, slipped down the depth chart behind free-agent Walter Curry in the team’s most recent OTAs and could find himself in a heated battle with Curry, Joe Cohen, Melvin Oliver, Atiyyah Ellison and ex-Eagle LaJuan Ramsey for the final two spots on the roster. We hear the Niners like the potential of Ramsey, a late bloomer who didn’t start playing football until his junior year in high school.
