In the end, our biggest problem is a lack of pass rush without a doubt. Rogers is a big boost to that as I think the addition of him helps with the DE's as well. Geathers was always next to a bum of a DT.
Our pass rush issues resulted from a lack of interior pass rush, lack of DE pass rush and lack of LB pass rush... So basically it just sucked. Rogers helps the interior part out immensly, I think he'll have at least SOME impact on the DE's and whoever we bring in at DE will likely be more of a pass rusher than a run D guy like Justin Smith.
