Obviously Stewart's holdout has grabbed the spotlight, but it might be worth noting that Knight isn't signed either, like most of the rest of this year's second-round picks.
I think a Knight holdout would be worse than a Stewart holdout at this point. Knight got raves in offseason works earlier this year and he is already pretty much locked in as the starter opposite Wilson. Meanwhile, Stewart was looking like much more of a rotational piece in the d-line, at least to begin with. Hopefully some other team can come up with a creative solution to the issue. Gawd knows it won't be the Bengals.
