The Giants are setting a high goal for Eli Manning’s completion percentage this season. A very high goal.

Giants quarterbacks coach Danny Langsdorf told reporters today that he wants Manning to reach a 70 percent completion rate this season.

Frankly, that’s preposterous. Manning completed just 57.5 percent of his passes last season, and his career completion percentage is 58.5 percent. The highest rate he’s ever had in any season was 2010, when he completed 62.9 percent of his passes. Unless the Giants are planning an offense that consists of nothing more than dump-offs to running backs, the idea that a career 58.5 percent passer is suddenly going to become a 70 percent passer is silly.

A 70 percent completion rate has only been reached five times in NFL history: Twice by Drew Brees and once each by Ken Anderson, Steve Young and Joe Montana. It’s less common than a 5,000-yard passing season or a 2,000-yard rushing season.

Maybe the Giants also have a goal for Rashad Jennings to rush for 2,000 yards this year. But that goal wouldn’t be any more unrealistic than Manning completing 70 percent of his passes.
