Which Falcons defense is legit? The one that completely shutdown David Carr and the Raiders or the one that made Taysom Hill look like a legitimate QB? It’s hard to know for sure, but rivalry games tend to go completely off script - so these comparison may not ultimately matter.
That said, this nugget is very interesting:
The Falcons have gone from 27th in pass defense DVOA in the first half of the season to fifth since Week 10, from 19th to eighth in run defense DVOA, and third in total defense DVOA since Week 10, up from 18th.
