How do you know? Do you watch every snap of every single NFL game multiple times? These guys do.
I thought Hayward was our best DB this year. He was spectacular. I'm not going to go as far as to say he's definitely better than Tramon, but he was better than him this year for sure. Hayward had more INTs, more defended passes, less TDs allowed (at zero) while playing considerably less snaps than Tramon. Tramon was %-wise targeted more often, and allowed more catches and yards per snap than Hayward. Though, one must consider that Tramon was covering the opponent's best guy more often than Hayward.
From what I've read (they have good articles too where they explain a lot of their grading and how that grade manifested itself during the games) it's a very reliable site in terms of evaluating players' performances. I don't think they know everything or have the perfect system for grading player performance but it's better than any other site I've seen.
