Cornerback has been one of the true priorities of the current regime. When you look at total dollars and draft picks spent on corner, it stacks up against most any position you can think of, and probably exceeds every single other position on defense.
What have the Falcons gotten for that investment? A couple of Pro Bowl caliber players, some players with bright futures, and a whole bunch of solid but unspectacular players who held down their positions for multiple years. The Falcons have, by virtue of their attention and prioritization, consistently put at least solid players out there at corner, but aside from their amazing luck unearthing Brent Grimes early on in the run, they’ve done their best work over the last six years or so.
