I doubt we get anything but negative information about the O-line. Not that I think it will be negative but what can you really learn from a group of 2nd and 3rd stringers who are playing against 2nd and 3rd stringers that's positive? If they play well you only know they're better than the other team's defensive depth. Of course if they play poorly it tells you that it would be wise you to stock up on alcohol and other assorted brain medications to gird you for the long season ahead. It's always good to beat the rush.
