I think the coach blew the game. There was a bad spot early in the game on a Vikings first down at their own 20, which might have been overturned if challenged. Then he uses a challenge in the second half, where the Vikings receiver actually had three steps before he went out of bounds. They also wasted an early time out in the second half when they couldn't get the play off in time.
Then, down 6 in the later stages of the 4th, he doesn't trust his kicker (who is 5 for 7 from 50+) to kick a 58 yarder. Elliott was viably disappointed, not so great for his confidence. If he would have made that kick, it would have been a 3 point game. Keep the Vikings out of the end zone on the following drive and a touchdown wins the game.
Two red zone drives were ended inside the 20, one by a terrible dropped pass by Smallwood and the other by an Ajiyi fumble, they left 11 points on the table on those two drives. Wentz is still getting hit way too much. Another winnable game given away. That ruffling the passer call on Bennett late in the first half, which maybe cost them another 4 points, was just a horrible call...
