Giants' two time Super Bowl winning quarterback Eli Manning had his struggles early last season in new offensive coordinator Ben McAdoo's system. He had previously been in the same system his entire career. By the year's end it had become clear that he was much more comfortable in the system. He finds himself even more adapted to the system this offseason. "This year, I understand the concepts," Manning said. "I'm still working on it, but I'm concentrating on the footwork and the mechanics and the timing of everything. It was great to have that this year and kind of get back to the basics of everything.
