Alex Smith is efficient and effective

The playoffs didn’t change anything with regards to how quarterback Alex Smith is playing for the Kansas City Chiefs.

Smith, who ranked second in the NFL in Total QBR since Week 7, was sharp in the Chiefs’ dominating win over the Houston Texans. It was one of the most decisive road wins in NFL postseason history.

Accuracy Chief

Smith completed 17 of 22 passes for 190 yards. His 77 percent completion percentage was the highest in a game in Chiefs postseason history, breaking the mark of 70.6 percent set by Len Dawson against the Vikings in Super Bowl IV.

Smith did throw an interception on his sixth pass of the game. He had thrown 119 passes in the postseason before throwing his first interception, the longest streak to start a career in NFL history, surpassing the mark of 115 set by Jeff Hostetler. Smith has 10 touchdown passes and one interception in his postseason career.

Déjà vu

Smith was 7-of-8 for 80 yards with one touchdown (to Chris Conley) off play action on Saturday.

He was 11-of-14 for 149 yards with two touchdowns off play action in a Week 1 win against the Texans. He had only two other play-action touchdowns this season.

Favorite target: Travis Kelce

Travis Kelce became the first tight end in Chiefs history to have a 100-yard receiving game in the postseason. He finished with 128 receiving yards, the most by a tight end in a playoff game since Zach Miller had 142 in the divisional playoffs for the Seahawks in 2012.

Kelce’s 73 yards after the catch were more than the rest of the Chiefs had combined (62).

Kelce had six receptions for 106 yards and two touchdowns in the Chiefs’ first meeting with the Texans.

Playing with a lead

Smith had the luxury of taking every snap with his team ahead, thanks to Knile Davis starting the game by returning a kickoff for a touchdown. Elias notes that it’s the first time in NFL history that a postseason began with a kickoff return for a touchdown.

The other guy had a rough game

The Texans stuck it out with Brian Hoyer and it didn’t go well. He finished 15-of-34 for 136 yards and four interceptions.

Hoyer completed 44 percent of his passes, the lowest completion percentage in a postseason game against the Chiefs since Joe Namath completed 35 percent and Daryle Lamonica completed 39 percent in 1969.

Hoyer is the first quarterback with no touchdown passes and at least four interceptions in a playoff game since Brad Johnson of the 2001 Buccaneers against the Eagles.
