Great point Mamba. Context is absolutely needed here. How many teams in the league can trot out their second team O line and dominate? Probably not many (if any). A backup can step in and do an adequate job if he's surrounded by starters. Over the past decade we've had to rely on the backup LT at some point every season and they've been decent. But when nearly the entire line is made up of backups then yeah, not great. Hopefully our entire backup O line doesn't have to start many games.
