ESPN's Dan Graziano reports the Giants have concerns Eli Manning is entering the declining stage of his career. Per Graziano, it's part of the reason why the Giants decided not to extend Manning's contract this offseason, which would have provided significant salary cap relief. The Giants are hoping that Manning is reenergized by the arrival of OC Ben McAdoo, but there's no guarantee he can rebound from the regression he showed in 2013. The Giants lost Hakeem Nicks and failed to upgrade at wide receiver or tight end in free agency, so Manning will be working with mostly the same supporting cast as last year. Manning recently underwent ankle surgery, but is expected to be ready for training camp.
