I'm not sure what that means, but it's not easy to pick against my Bills.
You waited until the last minute for something that should have been a no-brainer if you did the maths.
Pick the Bills
1. If Bills win: You finish first with two games ahead of second.
2. If Bills lose: You finish tied for first.
Pick the Patriots
1. If Patriots win: You finish first with one game ahead of second.
2. If Patriots lose: You finish first with one game ahead of second.
The above alone makes a Patriots pick already the better decision, but the benefits are even greater when third place and below are taken into account. A wrong Patriots pick wouldn't have hurt you, because almost everyone picked them, including all of your relevant competitors. But a wrong Bills pick would have costed you.
If you weighed the risk/reward ratios of all possible scenarios, then picking the Patriots was a really easy decision because it guaranteed sole possession of first place while the negatives were far smaller than with a Bills pick. But it took you the whole day and until the last minute to submit that change. I was expecting a change all along.
