The one glaring hole in that line is arguably the most important spot: left tackle. As we noted last week, Jonathan Martin has had trouble slowing down rookie Dion Jordan and second-year defensive end Olivier Vernon in practice. So how did Martin and his backup, Dallas Thomas, fare in their first preseason action Sunday against the Dallas Cowboys?
