The Garden was literally shaking.

As I sat in the corner of the parquet, two cameras in my lap, cross-legged in front of the who’s who of Boston in the front rows, I had an amazing view of the Celtics do-or-die Game 5 juggernaut.

And the fans almost lifted the roof off the place.

Charlie Baker, sitting directly behind me with his wife, fist-bumped me as the three-pointers rained down. To my right was former Celtic great Paul Pierce laughing and enjoying the accolades from the fans around him as he siped a cocktail from a straw.

To my left is David Portnoy, founder of Barstool Sports sitting stoically with his model-like girlfriend at his side.

I became well aware of the Heat’s confidence seeing them strut their stuff as they warmed up just before the game — but that bravado soon disintegrated.

Just before tipoff, Jimmy Buttler walked over to my corner in enemy territory to fist-bump a young woman sitting in one of the lavish floor seats. Glaring at the Celtics fans, he took to center court, grabbed the basketball from the referee, tested it by squeezing and bouncing it, then gave it back.

Then it happened. Seconds after tipoff the Celtics exploded! The passes were lightning-fast and bullseye accurate. Marcus Smart and Jaylen Brown were diving for balls, ignoring the probable demise of their superhuman athletic bodies.

Jason Tatum was effortlessly hitting threes and Derrick White was not missing a shot. The crowd erupted! The deafening sound coming from the Garden felt as though the building was rocking as the Celtics continued to dominate the Heat by not only their offense, but their cutthroat, do-or-die defense. Baker and his wife were on their feet along with thousands of others screaming with pure joy as the Celtics went ahead 10 points then 20.

Seeing the Heat crumble right before my eyes as the hometeam clung to life is something you witness only once or twice a season.  After the game ended Charlie Baker gave me a big double high five and said, “See you back here (on Monday)!”

The Celtics beat the Heat 110-97 and head back to Miami for Game 6.
