A few observatons:
There is only one catagory where the Pats are better than the Bills (Penalties)
The Bills are actually a better running team than the Pats .... will never hear that from the talking-heads
Many categories are close, but the two biggest disparities are Average Yards Per Game and Opp. Average Rushing Yards Per Game - Those are also two of the most important categoiries - Again, about the Talking-Heads, should not the question be: "Can the Pats slow down the BIlls rushing attack?"
The differences are not huge in any area, but the total is clearly to the Bills advantage.
