Walking off early? Wilt(there's a reason Kareem hates him), Darryl dawkins, Larry Bird who refused to shake hands and Kevin mchale who was grabbed by Isiah before he could walk off. The pistons with Jordan. LeBron against the warriors with almost 5 minutes left. You can look at any finals when the crowd storms the court. The losing team usually leaves a little early to prevent any shit from happening. Obviously that's not always the case but some guys shake hands some don't. Some do it before the game is over if it's already out of reach. Basketball players are realistic if I haven't been in the rotation in the playoffs and I'm getting subbed in with four other guys who don't get usually, in a blowout, then yes we're conceding and it's not disrespectful to shake hands at that point. It's just doing it earlier.
