The New York Giants are generally considered one of the best organizations in the NFL when it comes to the job they do in the NFL Draft. Does the data support that impression?

An exhaustive study from Draftmetrics, posted Wednesday in the National Football Post, indicates that would actually be a fallacy. Over a 10-year period (2003-2012) Draftmetrics ranks the Giants 11th in the NFL in terms of draft success. Over the past five years (2008-2012), however, Draftmetrics' analysis has the Giants ranked only a poor 29th in terms of the value they have received from their draft choices.

That five-year ranking is, really, pretty awful.

How did Draftmetrics arrive at these rankings? Draftmetrics is using a system that measures four things: Total number of games started by draft choices over the studied time periods, number of drafted players active for the 2012 season, average share (percentage) of annual starts by draft choices, number of drafted players named as original selections to the Pro Bowl.

Draftmetrics' research shows that the Giants have gotten 349 starts from their 39 draft choices over the past five seasons -- 26th in the NFL. The Giants were also 26th in the league in 2012 in terms of draft choices remaining on their roster over that five-year period at 64.1 percent.

Here are those last five drafts by the Giants:

This might change in the 2013 season, but only one player from the last two drafts -- 2011 first-round pick Prince Amukamara -- has become a regular starter.

The Giants have been hurt by injuries to players like Terrell Thomas, Kenny Phillips, Andre Brown and other players. They have also had misfortune with Chad Jones.

There have also been several choices that, to this point, simply have not worked out. Linebacker Bryan Kehl in 2008, receiver Ramses Barden, tight end Travis Beckum and linebacker Clint Sintim in 2010, Phillip Dillard in 2010, and thus far Marvin Austin (second round), Jerrel Jernigan (third round) and James Brewer (fourth round) in 2011.

There have been successes like Hakeem Nicks, Jason Pierre-Paul and Linval Joseph -- and it looks like the 2012 class could eventually be very productive, but there are too many disappointments.

You want reasons why the Giants have been so maddeningly inconsistent over the past few seasons? The hit-and-miss nature of their drafts has to be considered one of them.
