We haven't even gotten Gilmore's replacement yet, of course we look a lot worse now.
I think AW for Hyde is a wash as AW could never play consistently (injuries, not talent) and Hyde appears to be the one who will be getting the defense set and making the play calls, which is one of his strengths and was a huge problem for us last year.
Lets see who we get to replace Gilmore before we can make a definitive statement. If we are going with just Darby and Seymour then I don't know how anyone can say we got better. However, I do think we can find someone who fits this D for a decent price who will provide similar to Gilmore.
The thing is the scheme change a lone should be the biggest improvement imo. While losing Gilmore sucks, I don't think it is as drastic or detrimental to the team as some are making it out to be
