The thing most often forgotten during the excitement of the NFL preseason is which players left your favorite team, as every newcomer is looked through the optimistic prism of an "improvement" or an "upgrade."
In the case of the Giants, Nate Solder, Patrick Omameh and Will Hernandez are three new starters on the offensive line, but they replaced three players (Weston Richburg, Justin Pugh, D.J. Fluker) who other teams found desirable on the open market.
Same thing at linebacker — where the Giants added Kareem Martin but said goodbye to Devon Kennard in what could be described as an even swap — and so on across the depth chart.
