I'm having trouble with your Hyde and Hughes takes. Especially Hyde. No way McDermott (and Frazier) part with Hyde this offseason. That dude is essential in ways stats can't convey.
Hughes is NOT "done," as you say, both statistically and intangibly. Sacks can be a little like home runs, analytically, in that they can be misleading (baseball isn't a great analogy for football, but hopefully you get my drift). Some players sacrifice steady production for occasional, all-or-nothing glory. Like Jordan Phillips did in his contract year: terrible stats in basically every category except sacks.
I WILL agree that at some point soon Hughes WILL be done, and a team can get better sack production from cheaper options. But I say let him play out his contract as the veteran rock of the DE group. Hyde, too.
