If anything, Buzelis (or his agent) is hurting his value by going full keyboard warrior. that's an orange flag to me. Social media drama is definitely the kind of things GMs are attentive to with these young prospects.
And claiming you're better than another top prospect, when you proved nothing, is just not very smart and shows more insecurity and attention seeking than anything. Like Scoot claiming he should be the #1 pick in his draft. Some guys liked his confidence and that "dawg" back then... You can be humbled quickly.
Not to mention BB is a 5x5 game, not 1x1. Even being better on 1x1 (which remains to be proved) wouldn't necesseraliy make you a better prospect. Some guys kills it on the playground on 1x1, but can't play organised, team ball.
So yeah, badly inspired, counter-productive move by Buzelis.
