The San Francisco 49ers enter the draft looking to improve their offensive line but there are no guarantees the 49ers will select a lineman in the first round, as a run on offensive tackles is expected before the 49ers' turn to select with their 13th and 17th overall picks in the first round. It is conceivable the top four offensive tackles, Russell Okung (Oklahoma State), Trent Williams (Oklahoma), Bryan Bulaga (Iowa) or Anthony Davis (Rutgers), will already be off the board when it's the 49ers' turn to select. It is believed the 49ers would take either Okung, Williams or Bulaga in the first round but it's less certain how they evaluate Davis or any other draft-eligible tackles. Source: USA Today
