Interesting, I wonder if Mayo will replace Maroney as the most polarizing player to Patriots fans...
Personally, he seems to me to be on the good-not-great career path. He's fast, a good tackler, but only has OK instincts and doesn't seem to be a big hitter.
It's hard to argue with 16 tackles, but that was the quietest 16 tackle game I've ever seen. He doesn't seem to make picks or sacks or tackles for a loss. He doesn't seem to be able to meet running backs in the hole.
That all said, I still think he might be good. He is more of the kind of player who makes sure that a 5 yd gain doesn't turn into a 15 yd gain. That isn't showy, but it's valuable. He seems to give a big cushion in coverage and allows a lot of catches, but at least he keep the play in front of him.
Maybe that's OK. The best plan may be for him to leave the playmaking to others and be the person who makes sure to map up any of their mistakes.
