Giants show resolve in season-saving comeback: 'We all knew what we had to do'

The Giants came from 20 -0 down to beat the Arizona Cardinals 31-28 in the first half .

"You only have one way to go when your back is against the wall," Sterling Shepard said.

The Giants ' offense finally clicked into gear after halftime.

Daniel Jones , their $160 million quarterback, looked like the franchise quarterback the Giants think he is.

It's early, but it's far better than the alternative than being 0-2 and that second half was as bad as the first .

Now at least there's life. There is joy. There's even "belief," as Daboll said.

It at least gives the Giants a chance to become the team they thought they'd be.
