Atlanta Falcons have top CB tandem

Vontae Davis threw down a proverbial gauntlet a couple of weeks ago when he said, "I'm going to go out on a limb and say [Sean Smith and I] the best [cornerback] tandem in the league."

That statement did not sit well with Darrelle Revis, as he is of the mindset that he and Antonio Cromartie are the best set of starting cornerbacks in the NFL.

Philadelphia Eagles backers wouldn't agree with either of those two, as they would say the combination of Asante Samuel and Nnamdi Asomugha is the best.

So who is correct? Rather than settle this via opinions, let's put it to the metric test.

To make it even more interesting, let's open the competition up to four other teams with highly talented cornerback tandems: Atlanta (Brent Grimes and Dunta Robinson), Green Bay (Tramon Williams and Charles Woodson), Kansas City (Brandon Carr and Brandon Flowers) and San Diego (Antoine Cason and Quentin Jammer).

Each of these seven cornerback pairings will be graded in six different metric categories. The top group in each metric will receive a varying amount of points for its ranking in the category.

Category No. 1 -- Yards per attempt versus yellow-rated wide receivers

The yellow rating is one that is used throughout the Football Scientist material to describe a solid/good wide receiver. From a metric perspective, it means a wideout who gained anywhere from 7.0 to 8.9 yards per attempt (YPA) last season. Top-level cornerbacks should be able to keep this level of competition in check.

The point totals are seven for first place, six for second, etc.

Here are the rankings:
