I believe all the 2011 free agent acquisitions have helped the 49ers this season. The only acquisition I'm not sure about is Goodwin replacing Baas. I don't have any stats (ie sacks given up or tackles for a loss given up) to compare Goodwin vs Baas. I know Baas missed one game already for the Giants with an injury whereas Goodwin has started and finished all the games for the 49ers. I think Goodwin is an upgrade although the pre-season the O-Line was terrible. Goodwin is also older than Baas.
Does anybody have stats or info to compare how these guys are playing, Goodwin vs Baas?
