Here is what SB Nation said in placing the Giants at 19:
The Giants are betting big that Ben McAdoo's West Coast system is just what Eli Manning needs to bounce back from a nightmare season. If the early returns are any indication, it could be a long year for Big Blue.
I can't really argue much with the Giants being middle of the pack, and probably slightly outside the playoffs in these rankings. The Giants have a lot to prove this season and, honestly, things could go either way. This could be a 5-11 team if they can't protect Eli Manning or pressure opposing quarterbacks. If they make Manning comfortable and the pass rush re-emerges maybe a 10-win season isn't unrealistic.
We will see over the next few months.
