Flip play objective in campaign

I did it on PS4 so don’t know the exact controls on other consoles. The trick is to push the R3 stick down while at the line of scrimmage to open the audible menu. Then access audibles and flip from there. You have to open the on screen menu while lined up in order to trigger it.

if i remember correctly, you got to use the right stick to switch which way the running back runs.
