Who steps up for the Arizona Cardinals on Sunday?

We know the situation as of this moment, Thursday afternoon for the Arizona Cardinals.

We already know they are without J.J. Watt and A.J. Green as far as starters go.

They could be without DeAndre Hopkins, Rodney Hudson for another week, oh and that Kyler Murray guy.

There are question marks abound.

Yet, the biggest question should be who steps up to take on the challenge?

Last week, the Cardinals fell short on offense, unable to overcome the lack of snaps from DeAndre Hopkins, and the mistakes made by his counterparts at the wide receiver position.

This week, if they are without both A.J. Green and Hopkins, their top two receivers in yards who makes the big plays that the Cardinals will inevitably need?

Christian Kirk has been a nice 2b wide receiver this season for the Cardinals, can he step into the role of wide receiver one for this week?

Can Rondale Moore bounce back and make a couple of game changing plays? Will we see more of Zach Ertz, in game three and out of necessity?

Who makes the plays on the offensive side of the ball this week? That is one thing to watch for when the Arizona Cardinals take on the San Francisco 49ers on Sunday.
