The organization does, however, question whether they already have witnessed the peak of Manning's career.
Of course there are doubts.
Manning led the NFL with a career-high 27 interceptions last season. His completion percentage of 57.5 was his lowest since 2007. His 2013 yards per attempt average of 6.9 is down 1.5 yards since 2011.
The extended slump is one of the reasons the Giants opted against extending Manning's contract this offseason, per Graziano. They want to see evidence of the 2009-2011 Eli before they commit to him beyond 2015 and into his late 30s.
If Manning doesn't turn his stalled career around under first-year offensive coordinator Ben McAdoo, the Giants are going to have to consider drafting his eventual replacement.
