Opportunistic Play from Colin Kaepernick Key to 49ers' Win on MNF

Quarterback Colin Kaepernick was the San Francisco 49ers' X-factor against the St. Louis Rams in Week 6 on Monday Night Football.

How could we argue anything else?

Kaepernick finished his prime-time performance with 22 completions on 36 attempts—good for 343 yards and three touchdowns against zero interceptions. The efforts combined to give San Francisco's quarterback a 120.5 quarterback rating on the evening.

Kaepernick's arm probably did not figure to be a factor coming into this divisional matchup. St. Louis' primary defensive weakness came against the run. Prior to the contest, the Rams were averaging 152.5 yards allowed on the ground. In comparison, St. Louis had given up just 769 yards through the air over four games—the lowest in the NFL up to that point.

Based on these numbers, we should have speculated that the 49ers would have utilized a heavy running game featuring Frank Gore and Carlos Hyde throughout the game.

But St. Louis' defense stacked itself up against the run, which held Gore and Co. to a total of just 89 yards on 30 carries.

With this hindrance to the 49ers offense, the task fell upon Kaepernick to generate the necessary offense to thwart the Rams and help keep San Francisco's recent surge continuing.

It did not start off the way San Francisco would have liked.

St. Louis got off to a 14-0 lead in the first quarter. The Rams' second score was the direct result of a Vance McDonald fumble, after which St. Louis was able to tack on another touchdown. At the start, the 49ers offense looked out of rhythm and failed to generate the necessary momentum to gain a lead.

But Kaepernick and the offense did not fold or crumble. It answered back.

A key turning point came in the waning seconds of the first half. Kaepernick found veteran wideout Brandon Lloyd for an 80-yard touchdown reception that brought San Francisco to within four points at the half.

"The ball landed right in my lap," said Lloyd via Cam Inman of the San Jose Mercury News. Lloyd beat cornerback Janoris Jenkins and hauled in the pass for a 49ers score with just 14 seconds remaining on the clock.

The pass was the longest completion of Kaepernick's career, per ESPN's Sports Center.

But the 49ers still faced a deficit heading into the second half. St. Louis still attempted to clamp down on Gore and the running game, which forced Kaepernick to take his chances through the air.

San Francisco notched two more touchdowns in the third quarter—both Kaepernick touchdowns.

Kaepernick's first second-half touchdown found Anquan Boldin at the 9:58 mark. 

Boldin beat Jenkins on the 11-yard reception. Following the game, Kaepernick described what happened on the play, via CSN Bay Area.

What makes this play even crazier is that left tackle Joe Staley was supposed to be a primary target for Kaepernick. But Staley was tackled by Rams defensive end Robert Quinn, negating the creative option. As the pocket collapsed, Kaepernick was able to scramble outside where he could eventually find Boldin.

Here is what Inman had to say about it:

"

Left tackle Joe Staley was supposed to be the primary receiver, only he got tackled by defensive end Robert Quinn. ...Kaepernick improvised in stellar fashion, scrambling to find Boldin in the back of the end zone on a pass that caught even Harbaugh by surprise.

"

If that score wasn't enough, Kaepernick finished off his incredible Monday Night Football performance by hooking up with Michael Crabtree later in the quarter.

Crabtree executed a double move on the 32-yard post play. Kaepernick had little difficulty finding him. San Francisco scored 24 unanswered points with Kaepernick's pass to Crabtree, who executed a John Taylor-like route, according to ESPN's Jon Gruden (h/t Andrew Pentis of 49ers.com).

The touchdown finished off Kaepernick's scoring for the game. He would have had another touchdown pass in the fourth quarter had it not been for tight ends Vernon Davis and Vance McDonald running into each other within the end zone.

Regardless, the night proved to be more than successful for Kaepernick and the 49ers offense. His total career numbers—provided by ESPN's Sports Center—puts San Francisco's signal-caller in some pretty lofty company, Hall of Famer Steve Young to be exact.

Kaepernick's maturation process has been a point of discussion ever since the 27-year-old quarterback received his $126 million extension during the offseason. It has even been a topic beforehand. Was his season 91.3 quarterback rating enough to help carry this offense?

Perhaps Kaepernick's Week 6 performance puts to rest some of that chatter.

Kaepernick took advantage of a Rams defense that was supposed to be much better than this contest advertised. He was able to find his targets, distribute the ball effectively and help carry the offense in what turned out to be a gritty victory over a division rival.

We'll see how Kaepernick fares a tough Denver Broncos team in Week 7. This challenge might be the true test of the 49ers' season so far. 

But if Kaepernick can maintain this momentum heading forward, San Francisco will be in a good position to possibly upset the defending AFC champions.

In the meantime, Kaepernick can enjoy having put up one of the most dominant performances of his career.
