Arizona shows up in Green Bay with a backfield held together by depth chart guesses. Jeremiyah Love's high ankle sprain was supposed to be the workaround for an already thin room, and now that workaround is hurt too, with Conner and Benson banged up alongside him. Whatever the Cardinals call a run game this week, it is Allgeier, Knight, and Kiner figuring it out live against the Packers.
That is the kind of situation a total exists to measure. A depleted backfield can mean a grinding, low-event afternoon where nobody wants to force anything into a defense that knows exactly who is left standing. It can also mean the opposite: a offense that abandons the run entirely and starts chucking it, forcing possessions and mistakes that put points on the board faster than anyone planned.
37.5 is the line asking which version shows up. The story is real. What it does to the number is yours to decide.
