I agree with what you said about option C. I wouldn't berate a kid for deciding to sit out like some people do. I would be thinking about my future too if I was in that position. I'm merely pointing out that sitting out the bowl game is considered "normal" and totally ok by some people here, while sitting out a regular season game would be considered taboo. And the logic for that thought process doesn't really connect. The bowl game matters, it factors into a teams ranking, record, recruiting, it is a long time from the draft like all other games, your risk of injury is the same in all games. But for some reason it's more socially "acceptable" for a player to skip the bowl than any other random game. I'm just saying it doesn't make logical sense. If Fant wanted to chose a game to sit out, maybe he should have chosen UNI or NIU, or a game where we didn't need him to win.
As a side note, when a college offers you a scholarship they are making an investment in you. Maybe you will turn out to be a stud and win them lots of games, or maybe you will be a complete bust who's scholly should have been given to someone else. That is a calculated risk the college is taking. But as part of that scholarship you are agreeing to play in all the games in which you are healthy and able, in exchange for the school's investment in you.
