& also that they didn't want there to be any controversy for the season heading forward if Isaac were inserted & things got even worse in Tempe.
They'd basically conceded the game by the end of the 3rd quarter, I think. If Cam has somehow won, I think they woulda declared him to injured too continue on the season (which would've been honest). And they woulda switched to Wilson, regardless.
I think they understand now that Wilson ain't gonna get them very far with what remains on the season. But they can play for pride — play to improve under their new QB — & play to ruin their rival's season.
