One thing I think many are failing to account for upon the 2nd & 3rd year players is that last off season was a total loss on any development. The lockout impacted last years rookies some, but I think it was a critical loss for players coming out of their 1st pro year.
Guys like Wilson and yes Neal both didn't have the benefit of working in the off season with the coaching staff and being pushed by the training staff.
My point here is simple, lets not completely write off these players at this point.
And why value either Muir or Hargrove?
Muir was a player that would have stuck with the Packers if at that point we didn't have a excess of DT at the time. He was then snapped up and played a considerable amount for the Colts. Should we expect a stout pass rush from him.. probably not, but from memory he has a decent burst and could play an important role.. rotation.
Hargrove, IMO, will do one thing here in GB.. he will be brought in to play DE on passing situations to provide push.. if nothing else to make the opposition at least respect if in the blocking scheme. Last season, the opposition could plan for single blocking our ends and allow more to be pushed out to the edge. If he can at least force the opposition second level of protection to at least look his way it will be an improvement over last season.
It might not be popular, but IMO, if your downs in a 3-4 can provide a push, it expands the DC ability to call "effective" blitz calls from a number of holes not just the edge.. basically pushes the protection into mistakes.
