Any lifeline is a fallacy. Teams make their own destiny. Or they do not.
I dont see this as a lifeline.
I see it illustrating the obvious. The Niner lost to the Browns, the Eagles to the Jets, the 3-2 Bills are in a struggle with the Giants and the Bengals started 0-3.
This league changes from week to week. While I won't believe we can beat the niners, or advance past the divisional round until it happens, I won't rule it out. There's just too much fluidity in the NFL, and we are months away from when it truly counts. Be healthy, and have momentum going into the playoffs and anything can happen.
It's easy to prognosticate with ample recency bias and look smart, but it's doesn't mean it's right.
