Both Miami and Atlanta made upgrades to their OL. Both still have players left over from units that were literally historically bad. So, they're both hoping that some bad players will improve to mesh with the guys they brought in. In my experience, making moves that are supposed to be "good enough" don't typically hit the mark. The best way to build an offensive [or defensive] line is to shoot for a superior unit with depth, not a sufficiently good one.

I don't know. It's going to be an interesting season for both squads. They're going to live or die based on how well they improved.
