Kevin Gilbride is no longer calling plays for Eli Manning, but the Giants’ former offensive coordinator still has the quarterback’s back. Following a national discussion questioning whether the two-time Super Bowl MVP’s career has already started declining, Gilbride called the debate “ludicrous.” Manning also had arthroscopic surgery last week on the left ankle he injured in the Giants’ season finale. “I think he’s gonna be fine as long as the supporting cast, he’s not a guy that can solve problems with his feet,” Gilbride said on “Pro Football Talk” on NBC Sports. “You have to give him a line, give him some time. He’s gonna throw the ball to the right person, and he’s gonna throw it accurately. “There’s been no deterioration of his arm strength, there’s been no lack of preparation and effort. I think he’s gonna be fine as soon as they solidify the offensive line … and as soon as they get somebody who is going to be productive for them as an outside receiver.” Manning led the NFL with 27 interceptions last season, while completing 57.5 percent of his passes — his lowest rate since 2007.
