Can someone tell me why the Pats are early favorites?

Hi. I truly have no dog in the race im just curious as im kindve a noob. The Rams all year were infront of the pats in offense and total defense..the only ranking i can find NE is ahead is run defense. 

Dont get me wrong NE has looked completely different in the post season .. the game against the chargers was a beat down.. as for today they beat the 31st ranked total defense one of the worst d in the NFL through the regular season. The Rams are unpredictable last week won off rushing this week obviously certain things panned out but they barely had a run game so who knows what they'll do pass or run?

Is New England only favored cuz of the history and etc of Brady and belichek? Or are they really a better team? I heard a theory saying the millions of idiots who dont watch outside of the super bowl tend to lean to the pats but i dont know if thats the case  here. Just personally I felt the rams would be -2 or 3 to start and it could end in a pick em but now i have a feeling could be pats upto - 3 or more before the big game starts.. 

Back to the question though other than brady is the goat whats the justification.. or is that jusfication enough... 

Because the Rams don't have Tom Brady!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

NEWS: Someone doesn't value their money and just decided to bet against the Patriots in the playoffs

Pats lost to Jax Det Pitt Mia.   4 teams that didn’t make the playoffs.  Rams were arguably the top team all year with 3 losses to No Phil Chi all playoff teams.  I’m shocked the Rams are the underdog.   

Because they will be the public team.

In the Superbowl the public makes the line

liar=one thing the cp book is not open at 2 am on a monday am, and cp entertainment doesnt have the balls to take a large wager, they get nervous with a three hundred wager..

Exactly LB 

Recency bias for "upsetting" the Ma-Awesome Mahomes.

My simple answer- If they set Rams as a favorite then more people would bet on them. They know how the public mind works.

So they do what is most profitable for them. I guess someone here posted that they DID actually open as favorites, but that is not reliable info without verifying it and really means nothing as the line didn't stick and public thinks it was Pats as the favorite.

I can't believe more of the public doesn't take the dog in the super bowl. How do they not see that dogs almost always win it?
