7.5 of those 31 sacks last year came from non-DL players. The dline produced only 23.5 sacks. This year the dline has produced 27 of the team's 32 sacks through 15 games. So there is improvement in sacks and pressure (most of it coming the last 4 weeks). That said I agree "very good" may be a little strong for what the line has been overall this year. It is definitely gotten better over the last month though and if it keeps on this trajectory could be a "very good" line next season.
