Yeah, that's how I saw it. His birds were still out when he had his hands at his thighs. So that tells me he WANTED to flip them the birds up in the air, but he sorta-kinda did it, hid it and then wilted and walked off.
Personally, I think people should feel free to flip the birds when they are fucking frustrated at crowds, other teams, police officers, grandmothers and whomever happens to be pissing you off at that particular moment, and it shouldn't be taken as an actionable offense. EVERYBODY'S lookin' for a takedown these days. Leave the frustrated basketball player alone. Let him blow off some steam.
Remember John MacEnroe raising living hell on the tennis court whenever he got half a chance? I miss those days.
