I think people forget that among our FA signings and draft additions at Edge, was Greenard and Van Ginkel and of course Turner. Our losses included Hunter and DJ Wonnum (who is now starting to break out for Carolina after healing from injury). At the time we plucked Turner in the first round, we thought we had a good one in Greenard, but my sense is that Van Ginkel was more of an unknown, coming off an injury that kept him out of minicamps.
Putting it into perspective, I think it appears that Van Ginkel is every bit the stud that Kwesi (and BFlo) thought he was, while he was a mostly unknown quantity to us. An embarrassment of riches (almost, at that particular position). Turner will get more snaps, and Gink and Greenard will get banged up as the season goes on.
Bottom line, I think that the emergence of Gink in BFlo's defense was the pleasant surprise, keeping Turner off the field more than anyone would have guessed.
