The Kansas City Chiefs' passing game struggled in the second half of the season but has seen a resurgence in the playoffs. Quarterback Patrick Mahomes has been efficient and mistake-free, leading the offense to improved performance. The Chiefs' offense has been more structurally sound and benefited from better playcalling and game planning. They will face a tough challenge against the San Francisco 49ers in the Super Bowl, but their recent success gives them a good chance to win.
