I don't recall anyone saying that Marcus Washington was anything less than a great signing by the FO from day one. Go dig out my postings and you'll see that I thought he was the most important acquisition in the off-season over Portis and Brunell.
Everyone thought Springs was a good signing as long as he stayed healthy - which he had not done for the past couple of seasons but has done so far.
Griffin has had a really good year in the past and then really mediocre ones after that. On the basis of his history, I'll wait until he does it one more time before I say that was a great signing.
Barrow cannot possibly be considered a "good signing" since he has yet to play a down.
Daniels has been in and out with injuries too. The best grade you could possibly give Barrow and/or Daniels at this poinit is an "Incomplete".
To show why this kind of question is unfair midway through the season, should we berate the FO for taking Sean Taylor with the #5 pick because he has not played that much and certainly has not played all that well so far? Oh yeah, and he's in trouble with the law too, that shows how big a bunch of dumbasses they are, right?
