What I'm saying is that it's not the problem right now. Math.
Rams only carried 8 OL... and one of them was Evans.. who wouldn't have been there, most likely, if Bruss hadn't gotten hurt.
I can understand if the argument is that you just don't think they devote enough resources to the Oline and that the overall quality isn't good enough.. maybe Edwards wouldn't be the starter.. maybe Allen would be the backup.. but the number of injuries have wiped out the on-roster depth. Period.
Once you're on practice squad, you're fair game for the rest of the league.
That third string center was on the practice squad.. if he was "good".. he would've been poached by another team.
So, no.. it's not a depth and draft issue at the moment. When they were playing with Shelton, Jackson and Edwards.. backups at two positions.. one of them the 4th guard.. they were doing a decent job.
They gave up one sack to the Falcons and one sack to the Cardinals.. that's fine.. especially for backups including a 4th stringer.
