opening super bowl line?

opening super bowl line? I predict: gb - 4 jets gb -2 pitt
I would think since the game is on field turf in the new Cowboys Stadium... GB-5.5 over either team.
Gb 4 jets Gb 1 pitt
GB 6 jets GB pk Pitt

will GB be chalk to Pitt? that would be surprising to me GB -3 Jets GB pickem Pitt
After the way they closed this out id be surprised if gb is favored v pitt
the greek gb -4 jets, gb -3 pitt
Opened Pack -2. Went quickly to 2.5 and 3/+juice.
That line seems high to me. I thought Pitt would be favored by 1 or 2.
Let's hope it gets to +3-110
