When you ask a grown man if he's OK, and his response is to immediately call his grandmother, that means he's not OK. You were completely dismissive of Vontae's response to your question. And that makes it crystal clear that you really couldn't have cared less whether or not he was OK. So if you didn't care if he was OK, why did you bother asking? You're obviously only pretending to care - probably for the cameras.
I know these are football players and the NFL is a tough business. And if being a dick works for you, then that's your prerogative. But don't be disingenuous by trying to appear as though you care about players when you clearly don't. It's deceitful and deters players with any self-respect from wanting to play for the Dolphins. If you're going to be a dick, then just own it and players might respect that.
