It came down to four plays.
1) Wentz overthrows Agholor early in the 1sr qtr for a long gain, maybe a TD
2) Jeffrey gets called for holding on a run to the 5, Eagles settle for a FG.
3)Wentz fumbles at the goal line, touchback
4) Pederson doesn't challenge an illegal forward pass by Wilson, Seahawks go on to score.
Besides the timid play calling in the 1st half and a ton of holding penalties, Eagles played a good game. It's not like it was a 30 point blowout.
They'll bounce back next week. Goff isn't as mobile as Wilson, defense should be able to rattle him into mistakes.
