The final four matchups are set:

In Baltimore, the presumed MVP Lamar Jackson and the Ravens, who also boast the best defense in the NFL, will welcome in Patrick Mahomes and the Kansas City Chiefs, who looked like they remembered who they were, Sunday night in Buffalo.

Across the country, the San Francisco 49ers, fresh off a sloppy victory over the Green Bay Packers, will host the Detroit Lions, a team and a city, with dreams of reaching heights the team hasn’t achieved in the Super Bowl era.

So today, Jason Reid joins us from Highmark Stadium in Buffalo, where he tells us what he saw at the ballpark in a frigid Orchard Park as the Bills and Chiefs clashed. And then walks us through the rest of the divisional round action from the warmth of his hotel.
