(AP) Still among the NFL’s elite, the Green Bay Packers have more positions than usual that could use an upgrade in the draft.  Perhaps they’ll even buck tradition by taking a running back in the first round.  Alabama’s Eddie Lacy is the only RB prospect projected to be worth Green Bay’s first selection, the 26th overall pick, but he’s a good one. The powerful Lacy has had injury problems and lacks top-level speed, but he rushed for 1,322 yards and 17 touchdowns for the national champion Crimson Tide last season.   The Packers haven’t taken a running back in the first round since Darrell Thompson in 1990.   Safeties, defensive tackles and offensive tackles could also entice them in the early rounds. They have eight selections total.
