"4. When there are LBs that are good at shedding blocks, you're gonna get a bunch of people saying they can't drop back into coverage and how that's what is most important."

Im not so sure thats the case. The trend especially in the NFC East looks to be heading in the direction of running attacks. The Redskins , and now Chip Kelly going to Philadelphia looks to me more like running teams that will attack off the Play action pass. SF ,Seattle a team on the rise is a running team as well. I think the landscape is shifting who is ahead and who is behind.
