^^^^ Yeah, agreed throughout, really. (hence this disclaimer that it was bordering on a pointless observation).
That said I do think at the price point it's pretty low risk/high reward. I also think the Hawks would (or should) like to get back to the d-line rotational depth they had two years ago. TBH I think I would have liked this signing more for the Hawks than I do for the 9ers, but it's really hard to say with them because we still don't know what the story with Justin Smith is.
Before Dockett, the 9ers d-line was down to maybe Justin Smith, two young guys (Carradine and Dial), two guys coming off of season ending injuries (Dorsey and Williams), a journeymen (TJE), a UFA (Purcell), and a redshirt 7th rounder (Ramsey) .
Basically, I like it as rotational depth (which the price point suggests), and because it decreases the likelihood they take Arik Armstead at 15. Beyond that, though, whatever. I do hope for several reasons (both skill-set related for Dockett, and for what it means about Carradine and Dial) that they didn't take him to replace McDonald if Smith is coming back.
