Sacks are only one part of evaluating an OL and you know that. Weber's lines were helped in this regard by having the TE and RB's consistently helping with pass protection. He was also helped with Doman's love of throwing short (very short) passes.

This year's offense has shown substantial improvement in passing yds/att, passing yds/gm, scoring (up nearly 8 pts/gm over the last Doman/Weber offense), rushing td's, rushing yds/att, blue zone scoring, and blue zone td's. These are all signs of an improved OL despite playing a few underclassmen on this year's line.
