It's been said that on wild card weekend, point spreads typically don't matter......meaning you should either pick a favorite to cover, or pick an underdog to win outright. I first heard that in the playoffs following the 2021 season, so I haven't gone back to see if that still mostly applies or not.
I will say that on a spread like Steelers/Ravens, it would be tough not to try to go for that middle ground of +10, even as bad as the Steelers offense has looked lately.....given the division rival history and all.
