The paid attendance at MetLife Stadium on an arctic (wind chill of 1 degree) Sunday afternoon was 76,269, but it appeared about 50,000 paying customers decided to spend their New Year’s Eve elsewhere. That did not sit well with at least one player after the Giants finished up their 3-13 season with an 18-10 victory over the Redskins. “Obviously the so-called fans weren’t out there, but I appreciate all the fans that came out to show their support,’’ Jason Pierre-Paul said. “Without them, it’s really just us. So, I appreciate the fans that came out. They didn’t have to, but those are the true Giants fans.’’
