One of the fun things about having everyone on the USA’s Men’s National Basketball Team all coming from teams in the same league is that the players all know each other fairly well and can dish out a bit of trash talk and playful jive.

Cleveland Cavaliers star rookie Kyrie Irving decided to get a little of that going against Kobe Bryant at a practice when Irving challenged the Black Mamba to a game of 1-on-1. Even better, he wagered a little money — for charity of course — on it, $50,000.

Oh, and there’s video of it as well.
