His issue isn't his footwork but its his arms. He doesn't fire them out fast enough to get a hold of guys and control them. The speed rushers get into him so fast that it's to late and he gets beat. Then the speed rusher comes with counter moves and he's really toast. Staley has the an issue with speed rushers as well but he fires his arms and get a hold of guys a lot faster and better.
When Davis first came out, one of his reported strengths was his quick feet. In his first two seasons, he fared well against speed rushers but struggled against bull (power) rushers. So he spent a lot of time in the gym, put on a few pounds but the overall weight gain now seems to have turned him into being better against the bull rushers but has cost him foot speed.
This is a good example of how limiting a power running game can be. Every defense will eventually put enough defenders in the box to stop power running no matter how big your OL is. (what Seattle does) In that case, you have to be able to pass. However, if your OL is comprised of huge run blockers who lack agility for a wide running game and pass protection, your offense will always struggle in key situations.
