OKay, I'm not that much interested in the Steelers, but got curious with many threads about their D, I found this number for Steelers fans:
10%: the number of TDs that Steelers D gave up for drives starting on the other side (not including the Miami game). In other words, only 1 in 10 defensive series from the other side of the field will lead to a TD. League average: ~1 in 6= 16.3%, with expected SD ~ 3.3%.
For reference, Pats' D: 16.8%.
This 10% is still good even with opponent strength normalization. It seems that their offensive TOs hurt the Steelers. I leave it to Steelers' fans to check their TO number below.
Bottom line: It is extraordinary. Steelers D is legit. Projected Pats' O TD efficiency: 25-37%, which is ~3-4.5 TD for 12 scoring drives.
