Kansas City pretty much puts to an end the bay areas historic run the last 10 years. Low key the boston area and bay area have had some of the best sports runs in recent and past history.
I don't see any of these bay area teams returning to play for a championship in the next decade. This is the best run the bay area has had since the early 70s to late 80s.
Over the last 10 years....
Warriors: 5 Finals appearances
Giants: 3 World Series appearances
Sharks: 1 Stanley Cup appearance
49ers: 2 superbowl appearances
