Rhodes scholars can make alot more than an above average NFL player.
Sorry, but this just isn't right. Information doesn't seem to be handily available for the jobs chosen by Rhodes Scholars, but I would bet that a large portion go into careers in academia or government. That means they make, in comparison to an NFL player, didley squat.
but over a 30 year career, he'll bring in all kinds more cash as Rhodes Scholar neurosurgeon than his brief stint in the NFL.
You discount two important facts:
1) in the NFL he would be making the bulk of his money in the next 8 years or so, where as a surgeon, he would start out in the hole and slowly grow his earning power. Money now is much, much better than money later.
2) Professional football players, particularly articulate players smart enough to win special scholarships, often have lucrative careers after football, in broadcasting, sales, or even government. His earning power from choosing football does not end with his football career.
In reality, the choice isn't between careers. Rolle can play NFL football, and Rolle can become a neurosurgeon. The choice is whether to accept the scholarship and let the Rhodes program pay part of the cost of his education. If he chooses the NFL, he can afford to pay it himself. If he chooses the NFL, he will finish his playing career with plenty of life in front of him to go get his medical degree. I doubt a Rhodes Scholar neurosurgeon makes any more than a neurosurgeon named Rhodes Scholar who turned it down to play in the NFL but then went back to med school on his own.
I don't know what I would do when faced with the choice, but there are some pretty strong arguments for playing in the NFL.
