The Steelers is an interesting matchup and the one I want to see. The same game last year was competitive with a better Bills team against Mason Rudolph. I still think the Bills might eek that one out, but it'd be a fun game. I think the Chargers are a year away from really competing with them and would probably get throttled. The offense just doesn't have the firepower to keep up. Herbo is my guy and I love what Harbaugh is doing with them so much, but they need a legit WR beyond McConkey.
If I'm any of these AFC teams hosting the wild card game, I'd want nothing to do with the Raven. I know they've had some rough games here and there, but they're well balanced.
