The issue isn't smoking weed, it's that they already had concerns about his character so this probably just made him not worth the risk in the eyes of many.

He's going to be playing with a major chip on his shoulder. Major lottery win for the team that takes him.
Also, if it really was his stepdad that posted that picture......do you really want that kind of baggage?

Best thing he could have done. Admit it's you. Say it was years ago, and you didn't post it. Someone is pretty dispicable.

Wow. Someone is ruthless. This is out of hand. Cost the guy 12 million and will bring sanctions to his college program. That's nuclear stuff right there.
