Just prior to tip-off of the 2017-18 NBA season opener between the Cleveland Cavaliers and Boston Celtics, LeBron James and Kyrie Irving wouldn't so much as share a glance with one another.

What a difference 48 minutes makes.

After Irving missed what would have been the game-tying shot in the Celtics 102-99 loss to his former team, the ex-Cavs star not only shared a hug with James, but performed the duo's old signature handshake. Irving then proceeded to perform similar elaborate embraces with his ex-Cavaliers teammates, including J.R. Smith, Kevin Love and Channing Frye, seemingly ending any awkwardness that still existed after Irving requested a trade from the Cavs franchise over the summer.

"Anytime you win a championship with someone," James said of Irving after the game, "you think about that moment,"
