The NFC East side lost their first six games of the year, but back-to-back wins have left them just two wins off the top of their division.
The quarterback told reporters: "I think we still believe. I think that's been a great credit to this team and coaches. It's coming in and fixing the problems and right now, these last two weeks, we've played kind of our best football.
"So we have to continue to build off that, we have to improve on a few things offensively, but obviously we've got some new guys in there and some makeshift running backs and different things. But guys have stepped up and done well and we're going to keep fighting and hopefully you never know what can happen.
"Obviously we're not making the mistakes that we were making earlier in the season. We're not turning the ball over, but we still have to find a way to finish the games a little better."
The Giants will face the Oakland Raiders after their bye week.
