Whats up with the player ratings for the Seahawks?

Is it just me or is there some downright disrespectful player ratings for the Seahawks compared to the Rams and Patriots? I would think the Rams had a better defense than Seattle and its not even close in reality! And New England appears to have a much better offensive line, linebackers and secondary which i think should be obvious to anyone who watched the super bowl that they most certainly did not have better units in any of those 3 areas. I dont understand how they could rate the way they do, Seattle was the best team in the NFL for most of the season and definitely for the second half of the season and throughout the playoffs and it seems to me that whoever rates the players is a Rams fan or something
