Can you believe it? Somebody pinch me. The 49ers are hosting the NFC Championship for the first time in 20 years. And the future couldn’t look any brighter. Saturday’s Divisional Game against the New Orleans Saints was an instant classic. In fact, that was the best 49ers game I’ve ever seen. It had everything you could possibly ask for in a playoff game: Memories of Montana’s magic. Whispers of Walsh’s wisdom. Echoes of the Eighties exaltations. Candlestick was shaking harder than the ’89 World Series earthquake. And this nostalgia never felt so good.
