The Atlanta Falcons defense could fairly be described as a work in progress. Arthur Blank targeted and recruited head coach Dan Quinn to replace Mike Smith because he fielded some outstanding defenses in Seattle. Whether that track record will translate into success in Atlanta remains to be seen.

Meanwhile, because training camp is still a couple weeks away, we're still in prognostication mode. Pro Football Focus is releasing their preseason rankings this week, and today they released their secondary rankings. Take a look.

Atlanta still has one of the better young cornerbacks in the league in Trufant, who ranked 13th in overall cornerback grades last season. Robert Alford had his best year yet in 2015, with a slightly above-average grade in coverage. The team has high hopes for rookie safety Keanu Neal (Florida) to fill the Kam Chancellor-like role of the defense, but the No. 3 cornerback spot is a concern, with Akeem King being the favorite after playing just 16 snaps as a rookie.

Cornerback depth is an obvious concern for the Falcons but I'm really at a loss here. They aren't nearly this bad. Luckily these pre-season rankings won't matter at all once the season begins.
