Long is one of a couple of offensive linemen worth considering.
I'm a bit of an offensive line fatalist. The Falcons were never going to have a great unit in 2015, but they can certainly at least put a decent one on the field, and a decent one would be A) better than what they've had over the last couple of seasons and B) enough to keep the offense humming along at a strong clip.
At this point, you're not really looking to add new starting options to the mix, or at least not Week 1 starting options.
