There was almost a clash of titans Wednesday night in Boston.

During a game between the Cavaliers and the Celtics, LeBron James came just inches away from having his 6’8″, 260-pound frame crush the most successful NFL coach of all-time. Midway through the fourth quarter, James leaped up to chase a loose rebound, but came away empty. As he landed, he lost his balance and went sprawling towards the fans and cameramen who were sitting courtside along the baseline, which happened to include New England Patriots head coach (and five-time Super Bowl winner) Bill Belichick.

Here’s a clip:

Luckily for Belichick, James was able to halt his momentum in time to avoid a huge crash. After the game, LeBron joked that he slowed down because he realized who he was about to crush.

“That’s why I slowed up,” James said after the game. “I definitely slowed up because I knew it was him. I’m not taking no legend out. I’m not doing that. I need to keep seeing him win. That’s pretty cool for me.”

James would finish the night with a triple-double (32 points, 18 boards, 10 assists), but the Cavs still lost 103-99.
