Wade, I see where you are coming from, but I disagree about him not being suitable for the #28.
I think there are a few other considerations at play here. Perry is one of the fastest, strongest DEs of the entire class. His numbers in two years of play are equal to or better than Coples, Ingram, Upshaw, Mercilus, Irvin and Jones. He's also a Junior. That is some pretty big production for two seasons, coming out early, and indicates room to grow. I think he is well worth the selection, and I believe he fell as a result of unfamiliarity, being a PAC 12 player on the West coast, more than anything. They just don't get as much attention and media blow up in general, especially mired in a USC program under restrictions, even though they played possibly better competition that most of the other players mentioned.
4 of Coples 10 sacks last year came against James Madison and Duke.
4.5 of Irvin's 8 sacks came against Marshall, UConn, and Louisville
9 of Mercilus's 16 sacks came against Arkansas St., Western Michigan, Indiana, Northwestern, a reeling Penn St. and Minnehaha.
The other thing is finding the trading partner. Sounds like Ted took offers to move both up and down, and didn't like what he was being offered to make a trade. He was protecting our interests, and he knew he absolutely had to hit with this pick.
I do think the soft press/exposure led both to Perry's falling on the boards, and this rather benign media response in falling into GB's laps without much splash and fanfare. Nick Perry is a pretty damn good pass rusher - and a great bookend for Matthews, and I doubt highly we could have gotten him mid to low R2, which is where I'm guessing Ted was getting offers for his #28. We surely don't need what I'm guessing would be the R4 throw in on that, to miss out on what we need now, and what many project to be a sure NFL starter at OLB/DE. An R2+R4 doesn't add up to our R1 at 28, and neither do any of the R2+R3 combinations, except for the top 10-12, and maybe those teams just weren't offering... enough. Maybe they like Perry that much. Sounds like a good pick to me, with great value and upside.
