As the title indicates, the guys over at Football Outsiders split DVOA (both OFF and DEF) rankings from Q1-3 and Q4. While this was done basically to highlight Tebow and the elite 4th Q OFFs (ATL doesn't do too badly here, btw, at #13. That does drop from there #9 ranking at Q1-3, however.), I think we'll all be surprised to see that the Falcons have the best 4th Q DEF according to DVOA.
