49ers' Kyle Shanahan not worried about ongoing narrative

San Francisco 49ers head coach Kyle Shanahan has been one of the NFL's most successful head coaches over the past five seasons but is still searching for a Super Bowl championship to complete his resume. 

Not only has he not won it, he has been involved in some pretty epic postseason collapses that have created a pretty negative narrative on his ability in big games.

He said this week that he is not really worried about that narrative.

"I deal with it the same way if we win," Shanahan said. "I celebrate with our team. I celebrate with my family and I move on with the rest of my life, which is being a father or son and coaching and working and doing all that. Narrative, good or bad, is just a narrative ... I just don't want regrets. I just want to do everything that makes sense to myself, that makes sense for our team. And when you do that, that's what I have found. 

"No matter how hard something is or good something is, you always keep perspective of what it really is. If you want your perspective to be someone else's narrative, good luck being happy in life. Or successful."

It is a good perspective, but Shanahan is probably tired of being asked about it and is almost certainly looking to give people a reason to stop talking about it.

As good as Shanahan's teams have been, some of his big game losses have been crushing. 

In Super Bowl LIV the 49ers had a 10-point lead with six minutes to play and ended up giving up 21 points to lose.

Two years later in the NFC Championship Game, the 49ers went into the fourth quarter with a 10-point lead in Los Angeles only to allow 13 points in the final 12 minutes.

He was also the offensive coordinator for the Falcons in 2016 when they blew a 28-3 lead to the New England Patriots. 

He will have a chance to change that narrative on Sunday. If he can beat Patrick Mahomes and knock off the defending Super Bowl champions he will have effectively put that big game narrative to bed.
