I do get what you're saying, and I appreciate the aspect we're looking at this. But every elite athlete I've known is generally does not let such emotional weight very much their performance.
There are times when you could do things by sheer willpower, but that is generally not the result with these athletes
Their switch is simply turned on for games regardless. I know they can be more focused or dialed in, I know that a certain level of coaching can make a difference, but I've never truly believed nor heard of a team where it was sheer focus for revenge to make a difference.
The Ravens have an outstanding chance to win because they are a solid team with good players. Theor coach has success in opening weeks and preparing. The Ravens also have a lot of experience in beating the bills and the regular season. There's no reason to doubt they can't this opening week.
Still, for no two rational reason I believe the bills will win. I don't think I have a basis for saying that because for many reasons I believe the Ravens should win but will not.
