Many of us can recall when Doug Pederson was GB's #2 GB . Today he is Philadelphia's Head Coach and his Eagles are a force . Pederson's Offensive Coordinator is former QB Frank Reich and his Defensive Coordinator is former Lions Head Coach Jim Schwartz .
Yes he is lucky that he has QB Carson Wentz , but the Eagles Defense is very good too . IMO , GB should take a hard look at this team and learn from them .
I think Jim Schwartz has been a good DC everywhere he's been. The Bills screwed up big time, by going with Rex Ryan over Schwartz as Head Coach (not only because the Bills were perfectly set-up for the 4-3 defense and NOT Ryan's 3-4 defense BUT) that defense had completely bought into Schwartz. I might of understood the Bills passing him over for an offensive mind, but a completely different defensive system and no offense was almost asking to be screwed.
Also something Schwartz has... good man coverage guys in a number of key positions.
But I think you need to look what Andy Reid is doing with his OL, which Doug Peterson took over to the Eagles. I'm not quite sure how, but it just seems like they're able to use a system to get the most out of protection system. I haven't been able to dig into it enough to find out if it's just being good and balanced, being able to run or pass to set up the other or what. Though part of it, especially seems to be a good TE match-up with both.
