The original "everyone's 1st priority is money" was a facile statement and doesn't have to apply to Trae or any freshman contemplating the jump to the NBA. But each of these freshmen also have to weigh what they would lose if they stay that extra year. Miles Bridges, a surefire lottery pick last year, returned to Michigan St for his sophomore year. I hope it works out for him. But what if he, for example, blows out a knee. That guaranteed contract is gone. That first NBA contract could set one up for life financially. That doesn't make this decision "all about money." It's potentially about financial security for many years, if not the rest of their lives.
The point is, why should anyone begrudge a 19 year old who has the chance to live out his dream and become financially independent doing it choosing to do that versus staying and playing on their college team 1 more year? I'd love for Trae to turn down that opportunity for 1 year to stay at OU another but if he doesn't, I wish him all the best.
