If you have one weak link in the O Line, you can usually cover it with scheme or positioning or whatever. When Sherrod messed up, he was probably the best or at least highest regarded of the second teamers, so he wasn't gonna get any covering up. Furthermore, part of that messing up was against the Rams first team DEs. At very least, he should be an adequate backup. I'm still rooting for him to outplay Bakhtiari and start, although after last week, that seems less likely.
