Tackle Derek Sherrod has an impressive record (5-1), but, because of the competition he has faced so far, it might be too soon to say he is performing like the player the Packers thought he would be before he broke his leg in 2011. Although the former first-round pick blocked Matthews on the first day in pads, he does not have another win over a projected starter and his loss came at the hands of undrafted rookie outside linebacker Jayrone Elliott.
