The Cardinals have lost four straight games, but the future remains exceedingly bright because of Kyler Murray.

The rookie quarterback had another stellar showing on Sunday in San Francisco. His 150 passing yards didn't stand out, but there was a lot of hidden yardage added on three pass interference penalties. Additionally, he carried the ball eight times for 67 yards and a touchdown, an average of 8.4 yards per carry, and didn't turn the ball over.

Murray registered a Total QBR of 93.3 for his performance, which was the second-best mark in the NFL this week behind only Buffalo's Josh Allen, pending Monday Night Football.

Murray now has the ninth-best QBR in the NFL this season, an impressive feat for a 22-year-old in his first NFL season. Murray is ahead of Kirk Cousins, Derek Carr, Tom Brady, Aaron Rodgers, Philip Rivers and others.
