I agree with you on the playing aspect of things.A guy like Vedral needs to look at the big picture of his life. He's been able to play in Florida for a year on an undefeated team. He's gotten some meaningful playing time for Nebraska. He has 2 years left.
He can decide to stay here and get his degree from a B10 school, or move on to a lower division school to get to "play" for another 2 years, getting his degree from a lower division school.
The kid's not going to get drafted or get a FA deal from an NFL team.
If I were him, I might explore the idea of being a slot receiver. With JD probably not coming back and much of the receiving corps new, he might find a role there that allows him to stay and help the team.
Your comment on getting a degree from a lower division school, however, I don't quite get.
South Dakota State is in the same FB division as Harvard, Yale, Princeton, etc....and I don't think people would say that a degree from Harvard is a degree from a lower division school compared to Nebraska. I doubt Nebraska is a tougher school to get into than South Dakota State.
