The San Francisco 49ers extended their winning streak to six straight Week 15, dominating the Cardinals, (). The home side stayed with the visitors for the first half, but the second half showing by the Red & Gold showed why the 49ers are the best team in the NFC.

And quarterback Brock Purdy was a big reason why.

Here’s what went down in the desert.

The 49ers Week 15 win got off to a less than optimal start, allowing the Cardinals to waltz downfield for six points.

QB Kyler Murray had it going early, hitting tight end Trey McBride for a two catches totaling 49 yards. Then, Murray scrambled for another first down to put Arizona in first and goal. Two plays later, running back James Conner cashed in the score.

7-0 to the home team.

San Francisco’s offense responded with a TD drive to their own to open the game. Purdy was the catalyst for that, hitting wideouts Deebo Samuel and Brandon Aiyuk early. Running back Christian McCaffrey also contributed, picking up first down rushes before breaking loose for 26 yards.

Now inside the redzone, coach Kyle Shanahan drew up a misdirection play-action pass, fooling the defense. Purdy scanned and found Deebo Samuel wide open down the left flank, lobbing it to him for the score.

7-7 was the score in a matter of minutes.

Then, San Francisco’s defense woke up momentarily.

After picking up 26 yards, Murray and AZ found themselves facing a fourth down and short. Relying to heavily on McBride in the passing game, Murray didn’t see Charvarius Ward sneaking up behind his target. The cornerback read the play and snatched the ball away, taking it to the end zone for a house call.

A 66-yard pick six for Ward, putting the 49ers up, 14-7.

The Cardinals didn’t roll over though, working their way downfield for a few first downs. RB Michael Carter was instrumental there, rushing for 27 yards on the drive.

Eventually, they were halted near midfield after Murray took a sack on first down. Unable to pick up the chains, kicker Matt Prater came on to make it 14-10 at the start of the second quarter.

The 49ers’ offense stalled out for a second after that, going on their lone three-and-out possession. Meanwhile, the Cardinals kept chipping away, using all four downs to pick up yardage. Eventually, they were halted once more, forced to have Prater come on to make the score, 14-13, midway through the second quarter.

Purdy and the 49ers woke up once more, going on a 10-play drive to paydirt. That didn’t come before a near catastrophic injury to the gunslinger though.

Working to pick up a third and five, the Arizona native moved up the pocket before finding fullback Kyle Juszczyk leaking out. The play resulted in a first down, but Purdy took hit to the hemet from linebacker Dennis Gardeck. Purdy was shaken up from the play, walking to the blue medical tent under his own power at the 4:05 mark of the second quarter. Sam Darnold came in for the time being.

That didn’t last long however, with Purdy returning to the game after only three snaps. He was diagnosed with a left-shoulder stinger.

The young QB went on to make magic, picking up a third down using the Samuel screen play. Then, Purdy converted another third down, this time with TE George Kittle. The gunslinger saw Kittle branch off of his defender and float it to him, resulting in a 19-yard catch and run.

A few plays later, Purdy found McCaffrey on the Texas route to make it another TD.

21-13, in favor of the 49ers at the break.

San Francisco got the ball to start the second half and took advantage. And it only took four plays to do it.

Facing a third and long, Purdy surveyed the field before finding Kittle open across the middle. The big pass-catcher barreled his way past the defense, picking up 35 yards in the process. Then, Purdy made more magic, spinning away from pass rushers to throw a beautiful pass to McCaffrey downfield. The backpedaling CMC leaped up and caught it, getting back up to his feet to walk into the endzone.

A 41-yard bomb that put the 49ers up two scores, 28-13
