If you look at the more recent SB's over the past 7-11 years, Patriots have gone 2-3 and in 4 out of 5 of those matchups have put up fewer rushing yards on the year then their opponent, 1 of their two wins was due to a fluke defensive play and the other win was due to an utter collapse by their Opponent (Falcons).

Yes Patriots have more experience in the Super Bowl, but in recent history they have not exactly dominated it.
Patriots 28 points (and that is being generous)
Rams more than 28 points (does it matter how many more?)
Goff MVP (better odds than ML)
