In fairness, losing Bulaga that early hurt a lot. I don't think he would have made a 20-point difference, but I think the game would have been a fair amount closer.
The 4th down sack and the safety are worth last least 10 right there imo.
But I'll put it more on the:
1) Running into the kicker penalty (3 points)
2) Only having 10 men on the field for a Seattle TD (7 Points)
3) Twice making 3rd down stops, only to give Seattle a free first down via penalty
4) Burning a TO for 12 men on the field
5) Inability to defend the read option (I'm looking at YOU Dom Capers)
6) Losing the turnover battle (I still think Jordy should have caught that)
