It appears Packers undrafted rookie Frank Zombo suddenly has a lot more going for him than his cool-sounding name. Taking advantage of a surprise start at right outside linebacker in place of a banged-up Brad Jones in Green Bay's Week Three loss to the Bears on a national Monday-night stage, Zombo just might be on his way to becoming a full-time starter. Aside from a roughing-the-passer penalty that negated an interception, Zombo had an impressive outing against the Bears, registering a sack and applying consistent pressure on QB Jay Cutler. Zombo has been making positive impressions since training camp, showing off a sweet spin move, an excellent feel for knowing where the quarterback is and a knack for finishing just about every play in which he is involved. But team insiders believe it's a bit premature to warrant him worthy of replacing Jones, who is still considered a better run defender.
