Kyler Murray wasn’t perfect, but in terms of passer rating, the Arizona Cardinals quarterback couldn’t have done better on Sunday against the Los Angeles Rams.

He spent half of the fourth quarter of the 41-10 home win watching Arizona’s offense under replacement Clayton Tune, after completing 17 of 21 passes for 266 yards, three touchdowns and no interceptions.

Murray did something unusual after the match: he tweeted a yawn emoji following the win.

According to the FOX broadcast, Murray became the third Cardinals quarterback since 1960 to earn a perfect passer rating of 158.3 (on at least 10 pass attempts).

Kurt Warner last did this in 2008 against the Miami Dolphins.

The statistic’s formula takes into account pass attempts, completions, passing yards, touchdown passes, and interceptions.

Murray’s previous best was 150.5 in 2020, during a 34-31 loss to the Miami Dolphins in November 2020.

Against the Rams in Week 2, which moved the Cardinals to 1-1 on the year, Murray added five rushes for 59 yards, which is not part of the passer rating calculation.

Arizona led 41-10 when Murray was pulled from the game. His first two touchdowns went to rookie wideout Marvin Harrison Jr., who caught four passes for 130 yards and two scores. All of that production for Harrison came in the first quarter.

Murray found tight end Elijah Higgins trying to score his third touchdown, giving the Cardinals a 21-0 lead early in the second quarter of the upset win over the Rams.
