It doesn't and it won't. People really need to understand, the world is entirely corrupt. To the core. EVERYTHING is about money. Every single thing. He's playing this year because Texas Tech has a ****ton of it. If he was playing at Sam Houston State, he'd be back page news and an example made out of. He'd never play a down.
Also, the NFL, how good is he? If he's really good, aka an NFL QB, aka someone who can make a franchise a lot of money, literally NO ONE cares about this "addiction". If he stinks, then he won't get a shot.
Corruption, power, and money. Nothing else matters. He was always gonna play this year because there's too much money involved for him not to.
The ONLY thing that *might* happen is the backlash gets too loud for Tech and they just say ***** it, get him outta here. But that's highly unlikely. Again, too much money.
