Obviously I can’t answer that question definitively. When DGB originally came to OU, we were told that the staff had discussions with him and his family about staying for two years (if he wasn’t granted eligibility this year) and it sounded like that was the plan.
I’ve been told that lately he has told more than one person that he is definitely considering leaving for the NFL. There are certainly a lot of things that could make the decision go one way or another. But at this point the impression I’ve gotten from people who are close to him is that he’s leaning towards heading to the league.
