that's what I was wondering when I first saw it too...if the illegal touching was called...would they overturn the recovery and give the ball at that spot to the Hawks or just add on the penalty. Not sure if I remember that happening before...but then...my memory card is full and slow
you know, whether or not the officiating crew could turn the ball over is something i hadn't considered.
i'm leaning ever so slightly toward "no" due to a scenario i remember from a steelers/dolphins game a few years back-i think it was the first season where plays with a player whistled down could be reviewed for fumbles which might have been 2009 (edit: it was 2010). the crew ruled that the steelers clearly fumbled but there was no "clear recovery" of the ball by miami and as such it was turned back over to pittsburgh who scored on the next play. i remember it because my uncle is a huge dolphins fan and he was shitting bricks over it for a week.
in this case though, there was a clear illegal touch which does not count as a recovery by an eligible player. however, the seahawks obviously did not have an eligible player recover either. i'm not too clear as to whether the crew could then turn the ball over to the other team after a replay review because doing that in real time would be contingent on a flag being thrown.
