The San Francisco 49ers have addressed their top three needs methodically during the first two days of the 2013 NFL draft.After drafting safety Eric Reid and defensive lineman Tank Carradine, the 49ers added a twist before taking Rice tight end Vance McDonald. They traded into the 55th slot, leaping over division-rival Seattle, which was scheduled to pick 56th. Coincidence? One division rival messing with another? You decide.The Seahawks then traded the 56th pick to Baltimore for the 62nd, 165th and 199th picks.
