The Rams are saying all the right things about the OL, but I think their actions (or lack thereof) speak volumes.
They could have kept Saffold if they wanted to and chose not to.
They could have added OL in free agency and didn't sign a single guy.
And the guys they drafted (Evans & Edwards) seem like they won't press for a starting role until 2020 at the earliest.
Seeing how the Rams are approaching OL for the 2019 season tells me all I need to know about their confidence in the guys they have. Could they be wrong? Sure. But Kromer has an excellent track record with offensive linemen, both in picking them and in developing them: if he's happy with what he's got then I'm happy!!
