The story of the LA Chargers' Week 4 loss to the New York Giants was the subpar offensive line play. That's what happens when a starting unit loses its three best starters and is left with the two starters who most fans wanted to get rid of in the offseason.
Still, the Chargers' stubbornness to add more offensive line depth in the offseason despite having the resources to do so is frustrating. The poor offensive line depth isn't just because of offseason complacency, though.
It also has to do with lack of development.
