Only four quarterbacks in NFL history have reached a 70 percent completion rate in a single season: Drew Brees (twice), Ken Anderson, Steve Young and Joe Montana. Brees' mark of 71.2 in 2011 is the highest ever.
Manning's career-high completion percentage was 62.9, a mark he set in 2010. The average for his 10-year career is 58.5.
Last season, Manning completed 57.5 percent of his passes, struggling all season with accuracy and throwing a career-high 27 interceptions. In January, now-retired offensive coordinator Kevin Gilbride said that the Giants' depleted offensive line made it "impossible" for Manning to function.
