Run defense could decide the winner of Super Bowl LVIII between Chiefs and 49ers

Run defense will be a crucial aspect in Super Bowl LVIII between the Chiefs and 49ers — in fact, it may ultimately decide the game.

Well, the Kansas City Chiefs are back in the Super Bowl for the fourth time in the last five years, which is pretty insane. And in Super Bowl LVIII, they’ll face the San Francisco 49ers franchise they beat 31-20 in Super Bowl LIV, overcoming a 20-10 third-quarter deficit to do it.

These two teams are decidedly different than they were four seasons ago. 49ers head coach Kyle Shanahan had quarterback Jimmy Garoppolo in a 1973 Bon Griese hair shirt for most of that postseason, because Shanahan knew full well that when you put the game in Jimmy G’s hands… well, you didn’t generally want to do that. Raheem Mostert and Deebo Samuel were San Francisco’s primary rushers in that game, because the 49ers hadn’t yet made their team-defining trade with the Carolina Panthers for Christian McCaffrey. Add in a second-year quarterback in Brock Purdy who can actually hit his weight in the NFL, and this offense is far more to Shanahan’s preferences than that one was.

As for the Chiefs, there’s no more point-per-minute stuff. Tyreek Hill is out of the picture, and most of Andy Reid’s most explosive passing plays with him. The Chiefs got back to the big dance with a highly uneven receiver group, Travis Kelce finding the fountain of youth at the right time, and a Steve Spagnuolo defense that now sets the tone. There’s also the efforts of second-year running back Isiah Pacheco, who generally runs at your defense as if your defense owes him money.

So, a point of discussion now, as it really wasn’t in that last Super Bowl between these two teams, is how the two run defenses will fare. Based on the tape and the tendencies, I would argue that the team winning that battle may well come away with the Lombardi Trophy.

Let’s dive into it.
