This is incredibly nitpicky (wonder what team you cheer for lol), but the overall complaint is still accurate - EA still doesn't do a lot of analysis for their ratings. Victor Hedman, someone whose defensive analytics have ranked among the worst defenders in the league for the past SEVERAL years, is tied for the highest defensive awareness rating among defensemen with a 93. It's gotten better over the years, but it's still a pretty significant issue.
In this case, I'd say it's more "Kyle MacLean" is underrated, rather than Rempe being overrated (although he's more deserving of a 76.) Most players who make NHL rosters get an immediate boost to be at least 74 minimum.
