Wentz's coach is new because the Eagles owner doesn't suffer losing for long. He fired Chip Kelly after two 10-6 and one 7-9 seasons. He fired Reid after his first losing season in 7 years and only his third in 14 years.
Goff has a coach who can lose with impunity, 4 straight seasons and counting, and get rewarded with contract extension discussions.
Fisher can lose as much as he wants, as long as he's doing the other things the owner wants. Pederson won't last long if he doesn't win.
