wind and rain in this one spells under. Rain doesn't affect the O/U as much as the wind...missed field goals, QBs flutter and/or sail or maybe curve....rain gets you slips for no, fumbled QB snaps...even the best offensive teams can be neutralized by weather....I'm not in Seattle, but looking at the weather charts and Pt1guard's summation makes me think this will be a slower game than you think...maybe something like 17-14...worth a shot
