The Giants' O-line for years was a rock, bound by its collective synergy and harmony. Now, that cohesion has taken a hit. C Shaun O'Hara and OLG Rich Seubert are gone, replaced by C David Baas and David Diehl, who slid over from left tackle. That's where William Beatty takes over, having been groomed for the position the past two seasons. Also gone: Shawn Andrews, who played a valuable role last season; expect Adam Koets, Mitch Petrus and Kevin Boothe to vie for the reserve spots. The good news is that the right side — ORG Chris Snee and ORT Kareem McKenzie — remains the same, but McKenzie has battled injuries the last few years and rookie OT James Brewer is not game-ready yet. It's a new group up front, and they will be tested right away, facing the revamped Redskins in Week One, the fancy blitzes of the Rams in Week Two and the loaded front of the Eagles in Week Three.
