When you win the turnover battle 4-0, I would hope the margin of victory would be greater than a 2 point nail-biter. But ugly wins are still ugly wins. I fully buy into the DVOA/Pythagorean wins as being more predictive of future success than actual win/loss, but all of that can be a bit dicey in-season. For now, bank wins, get the #1 seed and continue to work on your issues. I certainly have my concerns about this team, but an opportunistic defense and an MVP quarterback will always give you leeway to outperform your peripheral numbers.
There's time for all that discussion later.
