Dodson was unable to hold off Bernard in BUF, even immediately losing the starting role as soon as Bernard was available post-injury last off-season. Now SEA is moving on from him after moving him to WLB when they traded for Jones. I don't have PFF but am curious what his score looks like there. Based on his inability to hold on to starting roles in several situations now, I'm assuming he's JAG. Walker isn't exactly a stud but he's proven to be solid over his career ( +JAG+ ?? lol ) so I'm not overly worried that Dodson will overtake him. I agree with
@massraider that Walker is definitely a hold and, even if cut, did solid work for those of us that plugged him in a for a week or three.
I wonder if only about a dozen LBs are more than JAGs, not even including some high-profile IDPs. We've seen guys like Devin White and Shaq Leonard just fall out of the league in their prime ages recently. Would anyone be surprised if next year, guys like Zaire Franklin, Oluokun, Bolton, and Logan Wilson just didn't have starting jobs? I wouldn't - they're great IDPs, but they're not Roquan Smith or Fred Warner. Jordyn Brooks was a great IDP in Seattle, but my recollection is that his PFF scores weren't very good, and it caught up with him. Same for White in Tampa.
My problem is that I'm not great at figuring out who's going to be Demario Davis and who's going to be Jaylon Smith. Even in hindsight, was Shaq Leonard great, but injury ended his career, or was he just in a good situation and wasn't good enough to stand out when he moved teams? I don't really know. Maybe I'm talking myself into a PFF subscription - I wish they had an IDP-only package available so I could see Macri's articles and defensive player ratings.
We pretty much learned that the NFL thinks that Jones, Baker, Long, and Dodson aren't difference makers. I wonder how long that list really is (but I'm pretty sure Walker's on it too).
ETA: Maybe it's the position - like RBs, where only a handful can keep starting after age 28 due to the beating they take and the oversupply of competent rookies available.
