The Niners' Depth on Both Lines of Scrimmage Was Worrisome

I think the Niners depth on both lines of scrimmages was a little bit worrisome. It takes a long time to develop offensive lineman, right? And this is like year two for Nixacal. This is year two for Jason Poe. These guys are probably a year away from being ready to play, but they're an injury away from having to play. I don't know if that's the attrition of the Niners going through so many long seasons that they're just preserving it right now. They're waiting for when things get real.
