We have crowned a new champion. But now things are just getting started. The draft starts in eight days. We have a potential Giannis trade happening soon. We have a wild free agency coming. Let’s prepare for a fun summer.Knicks euphoriaBig party in the Big AppleBing Bong? More like Ring Bong. OK, that wasn’t as good as I’d hoped, and definitely don’t play that video at full volume at work. Not suitable.The New York Knicks did the impossible on Saturday night when they won their first championship since 1973. The Knicks had some good teams in the 1990s, and it felt like they were knocking on the door the last couple of seasons, but something always got in the way. And they kept tinkering with coaches or rosters. It felt like owner James Dolan was never going to deliver a championship to arguably the biggest franchise in the sport. Not the most successful, but the biggest.That was proved during the later stages of the Knicks’ NBA Finals win over the San Antonio Spurs. New York fans dominated the postseason the same way their team did. Appeared in Atlanta. Overran Philadelphia. Showed up in Cleveland. I witnessed it firsthand in San Antonio. There was a solid smattering of Knicks fans in Game 1. After New York came back to win that game, downtown San Antonio was overrun with Jalen Brunson jerseys. Knicks fans were about as loud as the Spurs fans in the Frost Bank Center for Game 2. They had flooded the road game.After OG Anunoby’s miracle putback in Game 4 to complete the biggest comeback ever in a finals game (29 points), the writing was on the wall for the Knicks coming through for the first time since “The Exorcist” was the biggest movie in the country. Their fan base infiltrated an opposing arena like I’ve never seen. I’m not sure anybody has seen something like this.Before Game 5 in San Antonio, I was standing near one of the tunnels, watching Pacome Dadiet warm up. I overheard a security guard say to some of his coworkers, “10,000-11,000 Knicks fans? The plaza is going to be nuts.” I thought there was no way this could be true, and the pregame hyperbole must have been flowing.As I walked the concourse, I started feeling like this might be true. Knicks fans were everywhere. As I overlooked the arena from the media section, New York fans were omnipresent. Frost Bank was as loud for the Knicks when they did something as it was for the Spurs. And by the time the Knicks had completed their fourth comeback victory in five finals games, it felt like we were in a junior version of the madness at Madison Square Garden following the Game 4 win.Social media was as present for the off-court stuff in this series as the on-court stuff. People wanted to see how New York would celebrate. And aside from a small number of people being inappropriate and concerning in drawing attention for fighting or throwing eggs at the Spurs, the Knicks fans delivered in every way. It reminded me of the Cleveland Cavaliers parade in 2016 that was truly special. Except … we haven’t even gotten to the Knicks parade yet. That’s happening on Thursday and will be must-see TV/social media.
