One of my Giants fan friends said "I don't know why they didn't go out and sign someone else" and I was like I've heard this song before.
The difference that as bad as Zach was after that Patriots game, he could at least complete some forward passes. You just had to prep a backup plan, especially since the rest of the roster was good, and it was so early in the season.
The Giants just paid Jones a ton of money, and he was always going to be the guy as long as he was healthy. Most teams don't have 3 quality quarterbacks, which is why I was fine with Zach entering the year as a backup. We just got unlucky that he had to play so early and for so long.
